Single crystals are grown from solutions using "spectroscopically pxirell NaCl and "specially Pure" KCI, KBrand K1. The concentrations of impurity centres, estimated from the absolute value of the absorption coefficients, are in the range 0.001 to 0.01 mole%. Phosphors activated by Sn and Pb form unstable solid solutions, hence before measuring they are quenched by rapidly cooling from a temperature of 650-700 OC to 20 *C. Polarisation spectra of the crystals are measured at 293.and 100 9K.

Polarised luminescence is observed along the y axis perpendicular to the exciting light. Measurements are made on these phosphors using different filters and the absorption and emission spectra are also obtained. The azimuthal dependence of the degree of polhrisation shows that the oscillations of the Sn++ and Pbl+ centres are orientated along the C4 axii;. The polarisation spectra have.ciomplex structures and are shown to be correlated with the activator absorption spectra. The polarisation diagram of KBr-Sn, measured for the long-wave- length absorption band corresponds to that of absorption and emission by electric linear oscillators Me - 7Ce). An analysis of the polarisation characteristics permits of a more accurate interpretation of the electronic structure of the spectra of mercury-like centres. There are 8 figures and 1 table.

Rare-earth ions, which give off a linear emission of complex structure, are most frequently employed as the probes. The author also notes that the so-called mercury-like ions (Ga+, Ge2l; In+, Sn21+, Sb3+ T14~ Pb2+, ]3i3+) may be used in investigating the physical processes in allcali halide c4stals. A detailed study of the spectral characteristics of alkali halide-crystals, activated with mercury-like Ions, has demonstrated that in these phosphors the -Asorption and emission spectra at 100K (for KC I-TI even at 4. 2K-).are continuous bands without an oscillating structure. The sharp difference in spectra for mercury-like centers in crystals of the tyNs A1MV1 and A1BV11', Card 1/3 .!ACCESSION NR, AT4020793 j which are structurely similar deserves careful attention. The purpose of the present work was to determine the conditions necessary for the observation of a vibrational struc- ture in the spectra of mercury-like centers. The authors have attempted to utilize Iluminescent ions for an experimental investigation of the vibrational processes in the crystals. The shapes of the emission and excitation spectra of KC1-33i, Ca3(PO4)2-Bi, CaO-Bi and CaS-Bi phosphors were investigated at 295 and IOOK. The phosphors with large Stokes losses (KC1-Bi) have continuous emission and excitation spectra. In the case of phosphors having relatively small Stokes losses (Cao-Bi), at 100K a series of clearly 1marked equidistant bands were observed against the background of the Continuous emission and excitation spectra. The authors discuss the characteristic features of the continuous and band spectra, and their electronic (ISO ';�3p, and 3pO --.- ISO transitions in B13+ centers) and vibrational structure. The hypothesis is advanced that the band spectra arise as the result of the interaction of the electrons with the localized modes of vibration which, in turn, interact with the crystal vibrations. The authors found, in conclusion, that mer- cury-like centers with small Stokes losses may serve as convenient luminescent probes for the investigation of vibrational processes in solid bodies.

The basic experimental data were obtained in investigating different alkali halido'crystals activated by Ga+, Int, T1+, G02+, Pb2+, Cut and Ad+ ions. A gonoral discussion oVtho luminescence confors in ouch phosphors has been published (N.H.Lushchik and Ch.B.Lushchiks Tr. In.-!ta fiz. I astron. AN EstSSR' No. 69 elsewhere 5, 1957), It Is noted that the character of traps formed by activators in determined ..primarily b the charge of the activator ion. For oxample, B13+ ions are readily re- 0 2+, Sn2+ and P 2+ -duced to DX and trap an electron in the process. Analogously Ge b ions in a KC1 lattice act as effective electron traps. A number of other cases of Ca d 1/2 L 28320-66 -ACC NR, AP6013084 F effective.electron trapping are mentioned with references to the papers describing the corresponding investigations. Mention is made of decomposition of atomic centers in ionic crystals,.and a table gives theyalues of the decomposition temperature for atomic Ag, TI and Cu.in different alkali halides. The question is then raised whether activator centers in-the some systems are also capable of trapping holes. Xpe Recent electron paramagnetic resonance studies and optical a riments indicate that silver at any rate is capable of forming hole traps In alkali halide crystals. Refer- ence is made to other studies and it to concluded that as a rule (and not as an exception) activator lunihascenco centers in alkali hslide crystals are capable of trapping both electrons and holes, so that in many c"es in alkali halide crystal phosphors lualnescence of activator centers Is observed as.,a result of both recombine- tion of electrons, with trapped holes,and as a reaultof recombination of holes with,- trapped electrons.

Excitation spectra of In activated XF, CaF2, Cao, Ca3(PO4)2- 3Ca3(PO4)21 K2SO4, KBr, and CaS phosphors and Tl activated KF, Ca3(PO4)2, and X2SO4 phosphors*are presented by way of examples and are discussed in some detail, different excitation peaks being ascribed to definite electronic trans- itions in the activator:lon. For the predictlo~x of the excitation spectrum of an unknown phosphor, use is made: of the equation %p/% a I + &Ejr relating the energy EF of an electronic transition in the free activator io4 with the energy % of the same transition in the same Lon when It Is bound in the host lattice. The coefficient a ACC NRt AP7004990 ~is tabulated for 7 different activator ions in 10 different host lattices. The table shows that the value of a depends strongly on the charge of the activator ion but varies little for different activator Ions of the same charge in a given host lattice. Regularities are also no'ted in the variations of a for a given activator ion in different host lattices. With the,aid of these regularities and the tabulated values, one can obtain an approximate value of a for a now activator Ion in a new host lattice and thereby prediet.the positions of the peaks In th4,excitation spectrum of the pro- posed new phosphors'.

Vinylizing ot pyrrolidone was affected in dioxins solution in the presence of potassium pyrrolidone in the autoolave under a pressure of 15 to 25 atm and at 125 to 13200. This method is easier than that proposed.by W. Reppe (Ref. 1, Polyvinylpyrrolidon, 1954l Berlin). The vinyl pyrrolidone produced was used for the synthesis of polymers which in the Leningradskiy inatitut perelivaniya krovi (Leningrad institute for Blood Transfusion) hive proved to-be good blood substitutes. Independently of this paper and almost at the same timep data were published concerning the synthesis of pyrrolidone from suooinic acid and ammonia via suooinimide (C. 19531 91851 Rev- Plastic$ 2, 110, 132). But also for this modified synthesiag the last part of the Tinylizing, affected under pressure and using acetylene, is rather diffi- oult. In a series of cases it was, therefore, of advantage to realize the synthesis without acetylene and without increasing the pressure (at g. according to the equation by B. Puetzer at al., J. Amer.

A method of analyzing was developed in which magnesium is bound with trilon B and in which nickel can be determined in the presence of larger amounts of Mg. It is important, however, that the trilon B solution is only added after all the other reagents necessary for the development of the colored nickel complex, otherwise a nickel complex would develop with trilon B and no coloring would occur. Trilon B added last, does not interfere with the coloring of the nickel complexq as is shown in the test results obtained (Tables 1, 2).

Universal Spintillation Radiometer_ ?Y(_-3 (RUS-3) Note 1. The Measuring Unit /7 1960, PERIODICAL: Pribory I tekhnika eksperimenta, No. 5, PP. 35 - 40 TEXT: The following requirements were taken into account in the design of the instrument% 1) small size, light weight and portability; 2) the instrument should be supplied from 110 - 220 V mains as well as from batteries or accumulators; 3) the measuring meter and the electronic circuits should produce an error of not more than + 30%; 4) the measuring range should extend from 1/2 to 10; 5) the instrument should not be affected by atmospheric or climatic conditions. The resulting instrument is illustrated in the detailed circuit diagram of Fig. 1. The input device of the instrument is a photomultiplier which is connected to the electronic unit by means of a cable having a length of about I m. The multiplier Is followed by an emItter-follower pre-amplifier, based on a Card 1/4 85339 s/i2o/60/000/005/007/051 E192/E382 Universal Scintillation Radiometer RUS-3. Note I, The Measuring Unit high-frequency transistor (cut-off frequency of 60 W/O. The emitter-follower is followed by an amplifier-shaper circuit based on transistors r1VI2 and hn 3 ' The first transistor acts as the pulse amplifier, while the second transistor performs the shaping of the pulse. The presence of the resistor in the emitter of nri 2 ensures that the amplifier is stable. The output pulse obtained from the shaping stage has a duration of about 10 jis and its amplitude is 7 V (when the supply voltage is 8 V). The shaping stage is followed by an integrating circuit which is preceded by an emitter-follower (transistor fln4 ). The integrating circuit-has three different capacitances which correspond to the ranges of 30, 300 and 3 000 pulses/see. The circuit is followed by another transistor stage which is connected to a microammeter which indicates directly the number of pulses per second. The upper portion of the diagram in Fig. I illustrates the supply sources for -the instrument, The Card 2/4 85339 s/i2o/60/000/005/007/051 E192/E382 Universal Scintillation Radiometer RUS-3. Note 1. The Measuring Unit photomultiplier requires a stable voltage of 1200 V. This potential is obtained from an oscillator based on a transistor, type r)3,-!3 (P3-V), and, a suitable transformer. This oscillator operates satisfactorily even with input voltages as low as 3 V. The current taken by it (at 3 V) is about 81 mA. The supply voltage produced by the generator changes by about 3% when the input voltage is changed from 3 to 10 V. It can be seen that the instrument can be supplied with battery voltages from 3 to 12 V; as regards the mains voltage,this can vary from 80 to 250 V. In order to cover this range of AC voltages it is advised that a ferroresonant stabiliser followed by a rectifier be employed. In such a system it is possible to reduce the voltage changes to about 8 V when the input varies from 80 to 250 V. Constructionally, the instrument is in the form of small units which can easily be withdrawn and repaired or replaced by new units. The overall weight of the instrument with a set of batteries is about 3 kg. A photograph of the Card 3/4 85339 S/l2o/6o/ooo/oO5/007/051 E192/E382 Universal Scintillation Radiometer RUS-3. Note I.

TITLE: The Universal Scintillation Radiometer VYC-3 (RUS-3). II. y- and P-Probes PERIODICAL: Pribory i tekhnika ekBperimenta, 1961,No.1, pp.86-91 TEXr: The first part of this paper is given in Ref-5. In accordance with the design specifications for the WIC -3 (RUS-3) radiometer, the dose-rate range of the instrument should be 1-250 jLr/sec. This corresponds to a y-ray flux between 1.6 x 103 and 4 x io3 y quanta/cm2see. In order to achieve the required accuracy of � 30% at the lower limit, it is necessary to record about 10 pulses over a time interval of T = RC = 3 see. it follows that the minimum recorded counting rate should be about 3 pulses/see and the efficiency of the probe with a 1 cm2 screen should be about 0.29.. Such a low efficiency can be achieved with an inorganic crystal of about o.1 cm3, or a larger organic crystal. For practical reasons a polyerystalline stilbene screen (phosphor), 25 mm in diameter and about 150 mg/cm2 thick, was used. The screen Card 11,5' 20689 S/12o/61/000/001/027/o62 E032/E1111 The Universal Scintillation Radiometer P'V_ -3 (RUS-3)- II. y- and P-Probes was produced by compressing stilbene powder under a pressure of 700-800 kg/cm2 at 100 OC. The design of the y counter head is shown in Fig.Z. The counter head consists of a cylindrical steel envelope 10 which serves as a magnetic and electrostatic screen for thell',A-f -25 (FEU-25) photomult:Lplier 9 The lid 17 can be rotated and carries a standard specimen of T1204 which has a half-life of about 4 years. By rotating the lid the standard spec:Lmen can be brought to face the phosphor 20 through a~ special aperture in the plate 13 - The standard source is used to check the operation of the instrument. The P-probe is illustrated in Fig-5. The phosphor 24 is again made of stilbene and has a thickness of 40 mg/cm2 and a total area of 100 cm2. It is mounted on the conical light guide 20 which connects it to the (FEU-29) photomultiplier 15 - The stilbene screen (phosphor) is covered by a synthetic film with an evaporated layer of aluminium 27, having a total thicknes.s of 4.5 m CM2. The probe is calibrated by means of a standard TiVO4 specimen 17 which is Card 2/S 20689 s/i2o/6i/ooo/001/027/o62 E032/E114 eUniversal Scintillation Radiometer PYC -3 (RTJS-'3). 11. y- and P-Probes located in'the ring 18 By rotating the ring the standard specimen can be brought to face an:aperture in the conical part of the envelope 19 and irradiate.a small auxiliary stilbene screen deposited on the conical part of the light guide 20 5: With the screen 26 in position, the P-probe can be used to monitor weak y-rAy:fields from about 0.02 ILr/sec. When the screen is removed *the device can be used to record P-ray fluxes bet-ween 0-15 and 8; p/cm2sec. When used in conjunction with a suitable specimen collector, it can be used to determine the concentration of P- and y-active gases in air in the range 10-10 to 5 x 10-8 c/t (L.M.. Mikhaylov and A.D. Turkin, Ref.12). The P-probe has a O/Y ratio of 50-80. An a-probe and a neutron probe will be described in a subsequent paper. Acknowledgements are made to N.A.

These specialists, for ipstance the graduates of the Agricultural Academy imeni Timiryazev had a poor knowledge of the methods of complex territory inspections because they had not been instructed on the method of examining quarternary deposits, were lacking in knowledge of geomorphology and were not familiar with methods of geobotanical examination. To eliminate these deficiencies the Soil-Agroahemical Faculty of the Academy introduced a complex practical training which was Card 1/2 carried out on training farms, in such subjects as soil Complex Soil-Agrocheinical Training Practio:-) 3-3-17/40 crust, vegetationp quarternary deposits, territorial geo- morphological characteristics, ground water and local manure. Started in 1956, this training had its deficiencies but will be developed in the future. It lasted 3 months and started with field and vegetation fertilizer tests. Then the method and technic of carrying out field and laboratory res)arch was explained and the water and physical properties of the soil wore studied. Studies were also conducted in geobotanyp geology and the other abovementioned subjects. The know- ledge acquired assisted the students to complete iuccessful- ly the soil-agrochemical research required in the course of their production practiceg and to obtain the necessary skill for independent work.

The method is.based on the theoretical predictions of A. Abragam (cryogenics v. .3, 42., 3,963) and C. D. Jeffries (Cryogenics v. 3, 41, 1963), wherein: ..th e spin temperature is rapidly decreased via spin-spin relaxation accompanied by rapid "oling of the systemo The authors verified this method with single crystal (La,, Ce)2M93(N03)1Z-24H2O,, and obtained an appreciable Increase in polarization. The experiments were made In fields from 2 to 6 kOe at saturation frequencies from .60 to 1TO Me with the crystal rotating uniformly at 30--600 rpm. The experiments were made at l*3K - Amplification coefficients up to 70 yere obtained. The ampli, 1/2.

The specimen was a single crystal.of binary lanthanum-magnesium nitrate La2Mg3(N03)12-24(H20 + D20) with a 1% Nd142 impur,ty. 1 Part of the ordinary water of crystallization in this crystal has been replaced by heavy water. Mass spectro" scopic analysis showed,a deuterium content in the crystal of 42%. It was found that polarization.in excess of 10% is possible in a magnetic field of 20,000 oer- steds at a temperature of 10K, which is much greater'than the 1.2% polarization attainable in solid deuterium.
