Thin angular distribution wan measured for proton energies of 120C, 140C and 1600 keV. The protons were produced by inuitna of an olt:ctrostatic Een~rutDr and after passing through a 90 degrees magnetic analyzer they w~,,rk! dii-cted up()n it tritium target. The system for the voltage stabilization of t~.Q iTenerator -~vur- rants a constancy of the proton energy which is accurate up to 2.10-2 A solid tritium target was used, and a long counter served as a detector. The proportion- ality counter had a firm coverine of boron and was filled with a mixture of argon and methyl alcohol. Next, the problem of the sensitivity of the 'Long counter with respect to neutrons with different energies is discussed in detail. 7iith the help of the obtained characteristic of sensitivity it was possible to measure the angular distribution of neutrons with more than 25 keV with great accuracy, i.e. for all angles at proton energies of 1400 and 1600 keV and for angles below 1520 (in the center of mass system) at 1200 keV. in the case of large angles and 1200 keV accuracy is considerably lower. Angular distribution was measured inside a cabin of 3 x 3 x 2,5 m, the walls Df which were coated with a mixture of paraffin and borax. In the center of the cabin was the tritium target. The long counter was located at the distance cf SUBJECT USSR / PHYSICS CARD 1 / 2 PA - 1T47 AUTHOR KOTLYPIN,E.A., MOROZOV,V.M. TITLE The Estimation of the Upper-Limit of the Cross Section of the Radiation Capture 7of Neutrons with the Resonance Energy (275 kev) by the Isotope Li - PERIODICAL Dokl.Akad.Nauk,111, fasc.2, 331-333 (1956) Issued: I / 1975-7 The authors used the continuous registration of P-decay acts of Li 8 when irra- diating lithium with neutrons. On this occasion the momenta caused by the a-particles of B98 deca are separated from momenta caused by the products of the reaction of Li 6(n,ti Hei. The a-decay of the Be 8 even occurs in the ground state within \,10-16 see, so that, from the experimental point aof view, this process may be considered as simultaneous with the P-decay of Li . The measuring device consisted of two gas counters. The inner counter (of usual construction) oper- ates as a proportionality counter, its walls are covered with a thin layer of lithium fluoride with a content of natural isotopes. The exterior counter registers the electrons of the P-decay of U8 and operates as a GEIGER counterl its construction is illustrated by a drawing. On these conditions the efficiency of6the reg. stration of the P-decay of Li 8 (with respect to the registration of Li (n,t)He ) depends only on the absolute efficiency of the counting of the electrons of the P-decay of Li 8 by the exterior counter. The efficiency of the exterior counter attains 50 T 10%.

The monoenergetic neutrons were obtained in the aforementioned energy interval from the reaction T(p,n)Hej'. The tritium was contained in the titanium-cover of a molybdenum target. Measurements were carried out in a 3 x 3 x 2,5 m cabin the walls of which consisted of a mixture of paraffin and boron. At from 0 to 600 the bKckground amounts to not Mo-e tha- some percents of the primary neutron flux. At large angles ( / 1400") the back- ,ground attained a noticeable part (up to 6o~;) of the primary neutron flux. For measuring the relative course taken by the cross section of tne reaction Li6(n,t)He4 the authors constructed a spiral-shaped ionization cha.~.iber with small dimensions. For the measuring of tYe absolute value of the cross !jection of Li6 n,t He4 three plane ionization chambers are produced; they contain tech- nical argon with a pressure of - 4 at, and have an operation voltage of 11 350 V. The pulse characteristics of these ,lune ionization chambers were fully satisfactory. Carrying out measurements is discussed in snort.

PERIODICAL: Deklady Akademii Nauk 33SR, 19'~;7, Vol 11,4, Nr 'D, PP 1939 - 1o42 (U.S~S.R~) A_BSTRACT: First of all some relevant preliminary papers are quoted. If the atmosphere is hoxizontally homogeneous, then (at monochromatic light with the wavelength A ) the equation of the searchlight sounding with consideration of the weakening of the light in the atmosphere reads as follows: a (h) exprip a (h) dh (h) a X e'~ Here ax stands for the coefficient of the scattering in the alti- tude h, and W for the angles of the elevation of the device and of the searchlight, respectively, We furthermore have X - (1/sin 0) + (1/,gin&j ). A photometer with a photoelement that was attached in the focus of a searchlight mirror served as light receiver. First of all a formula for the scattering coefficient is Card given which is valid at the following simplified conditions: a) The 20-5-26/67 On the Nonmolecular Scattering in the High Layers of the Atmosphere. searchlight beam has small angular dimensions and its image lies completely an the photocathode. b) The sensitivity at the surface of the photocathode is cornstant. But actually these conditions are not realized: a) The beam of the projector consists of a light narrow ray - the ray proper - and of a relatively weak but wide hinterground which ranges to angles of about 40 degrees. b) The sensitivity along the photocathode is not constant, This hinter- ground is taken into consideration by the introduction of an addi- tional term El 0 into the equation of the searchlif~ht sounding. This term is small as compared to the other terms of this equation. The approximate and the accurate expressions 111(h) and a 2(h) of the scattering coefficient, as found by the solution, are given., Then these expressions are transformed. With the aid of the method described here, it is possible to eliminate the influence of the multiple scatterini, of light.

It is shown that the mode interaction can be described by a set of rate equations and that the steady-state regime is stab.'.e. The solution i of the system of equations depends on the frequency difference o.1, the modes. The two possible cases, nearly biharmonic and nearly harmonic oscillations, are analyzod. In the case of close modes the steady-state regime may be unstable, resulting in the appearance of undamped spiking. The laser operating regime is shown to depend on the shape and position of the mirrors and the quality of the crystal. Orig. art. has: 17 formulas and I figure.

Doklady, v. 162, no. 4, 1965, 781-78h TOPIC TAGS: laser, stimulated emission, mode, laser theory, laser cavfty ABSTRACT: A theoretical analysis is made of the operation of a two-mude iaser. !Simple substitution is used to obtain an equation containing the polarization and i :the electric field from a set of equations for a one-mode laser. The equation cb- can be expanded in terms of the eigenfunction of the field. Two special .cases are considered: 1) eigenfrequencies much greater than the width of each of the resonance lines and oscillations occurring at both frequencies (nearly bihar- monic oscillat-Jons) and 2) resonance curves overlapping considerably (nearly har- :monic oscillations). In the case of nearly biharmonic oscillations, applicaCiou of ;van der Pol equations to the system of equations obtainect t)y the authors results in a set of rate equations which, under certe-in simplifying assumptions, are identical ~to those obtained by W. E. Lamb (Physical Review, v. 134, no. 6A, 1964, p. 1429). '-Card 1/2 L 3196-66 ACCESSION NR: AP5015414 In the case of nearly harmonic oscillations, application of van der Pol equations leads to a set of equations for slow oscillations. An analysis of the resultinE equations shows that the intensity of emission consists of regular undamped osci"_ lations and explains some of the experimentally observed operating regimes. How- ever, the actual regime is much more complex and requires analysis of the inter- action of a larger number of modes. Orig. art. has: 5 formulas and I figure.

However, fre- quency splitting A of the traveling waves takes place only at rates of rotation v greater than some critical velocity Vcr (or the corresponding quantity Acrl*2kVcr/", where V is the linear velocity of a resonator mirror, k is the wave vector). Cou- pling between traveling waves causes mutual synchronization at frequencies below the !critical value which results in single-frequency conditions.

A spectral analyzer was used for measuring the beat frequency &. The capture band Acr was studied as a function of ,the coefficient of transmission for the output mirror. A reduction in transmission 'causes a sharp change in the capture band. Experiments were conducted on attenua- tion of the beam reflected from the external mirror by using a filter. Attenuation of this signal reduces the capture band. Various optical system were used for passing the direct and reverse beams to the photoelectric mixer with a simultaneous .reduction in the energy reflected into the resonator from the external mirrors. :Figures axe given showing two modifications of systems for reducing the capture band ;to 300 cps. The Q of the resonator was reduced for a further reduction of the band. .This was done by replacing one of the opaque mirrors in the resonator with a semi- transparent mirror. The result was a reduction in the capture band from 300 to 50 cps at the same output power. The magnitude of the capture band is determined by the reverse reflection of energy from various elements -in the resonator, scattering by nonhomogeneous media,and the nonlinear dependence of polarization an the field. 11he authors are grateful to N.

PhYs., v. 34, 1963, 453) that regular pulsation of the radiation power with a frequency of an external force is obtainable Ina laser by means of a periodic modulation of losses in its resonator. The present article offers a theoretical analysis of this phenomenon. The fundamental equations of a Q-switched laser are replaced by this X3 approximate nonlinear conservative equation: x+x(l+x)-- =0; the motion 1+X integral of this equation is: x'=(I +x) JC+21n (I +x)-2xi, this integral defines the phase trajectories of the equation and permits solving-. UDC: 621.378.3 L 421'18~r6 kCC NR, AP6026934 the equation by quadratures. This equation takes into account interactions between modes and contains stable maximum cycles. The maximum cycles are due to small nonlinear losses which depend on the amplitude of oscillations and which arise as a result of modes interaction. In the case of a ruby, the nonlinear losses that I amount to about 0.0001 radiation loss through the mirrors may result In a stable maximum cycle. This cycle may be interpreted as a result of a mutual synchronization between phase-shifted modes. Several maximum cycles can arise in a multimode model, depending on the relations between the modes. Depending on phase relations, various time-intensity relations are possible. With random phase relations, the output will be irregular. "The authors wish to thank N. 0.

P ;P a -lie problem was limited to a one-dimensilonal approximation with the assumption that the photons which are emitted spontaneously over the steradians are propagated Predominantly alon~r the rod in two possi- ble directions. "he amplification of spontaneous emission wa7, described by a system of nonlinear partial differential equations. The results indicate that In the case of snort rode;, rair, )er increases exponentially with len,-th at 'Irst, decreasini, subsequently due to an increase in the probability of dumping of active particles by the spontaneously emitted photons. At hi,-,her amplification cf the Card 1/2 UDC: 621.375-9:535 L 4'~127-66 ACC NR: AP6026977 soontaneous emission, the total ~~ain o' tne crystal linearly depends on length. At pumping intensities of 5-10, increase in gain with length is effective from 15-20 cm, and at intensities of 10-20 from 10-15 cm. At increased rod lengths the average gain per unit length decreases monotonically, thus indicating the advantage of using a series of small noninterchangeable crystals Instead of one long one to achieve higher gains. The problem becomes highly complicated when crystal shape, reilection, transmission, and scattering are accurately known. In such cases the proposed single model can be considered as a first approximation of the problem. Orig. art. has: I figure and 2 formulas.

Doklady, v. 168, no. 3, 1966, 550-553 TOPIC TAGS: laser emission, solid state laser, laser pulsation, phase diagram, light, pulse ABSTRACT: The differential equation for the intensity of laser emission, which in thq case of solid-state lasers reduces to an equation whose stable limiting cycle cor- responds to undamped oscillations of the laser emission intensity, is solved analyti- cally. It is shown that the solutions obtained approximate quite closely the phase trajectories of the system in a case of large depth of modulation. The solution con- sists of two parts. The first corresponds to a slow motion when the active particles accumulate and the amplitude increases relatively slowly. The second represents an increase in amplitude followed by a release of the stored energy by radiation during a short pulse. The analytic relations obtained are used to calculate the parameters of a scheme proposed by the authors (Paper at Scientiftc Congress in Leipzig, March 1965) to obtain short light pulses (Fig. 1).
