Numerous chemical and spectral analyses of rocks and minerals have established that Nb and Ta are characteristic elements of the riven co--Dlexes. The average contents of these in the massifs of the Kola -2 -1 Peninsula fluctuate -a-ithin the range; 1.34-5.18'10 P Nb and 1-32-5-90-10-3 % Ta.

Their results have been reported on the All-Union Con- ference on X-ray Spectroscopy in Rostov-na-Donu, June 302 1959.

It is increased by nearly 50% owing to extension of the transmission end level of the photoelectron in the molecule. As was expected from theoretical calculations, a suf- ficiently intense band appears in the X-ray spectra of the metal in aro- matic complexes which is due to the transition of the Is electron of the absorbing atom to the grOUD of molecular levels of corresponding symmetry, in addition to a series of bands of the "exciton'l-type.

Fine structure of X-ray absorption K-spectra of titanium in complex solid solutions of the TiC-TiN system PERIODICAL: Akademiya nauk SSSR. Doklady, v. 140, no. 3, 1961, 56o - 562 TEXTt This is a contribution to the extensive experimental and theoretical material on carbides and nitrides of transition metals. S.

The K-absorption edge of titaniumc'was examined with an X-ray spectrograph (G. V. Samsonov et al., Dop. AN USSR, 1, 838 (1958)). The analyzer was a bent quartz crystal, in which the (1071) plane was the reflecting plane (radii of curvature, 2600 and 1650 mm). The X-ray photon energy was determined with an error of + 0.3 ev. K-absorption edges of 7 alloys of the system under consideration, averaged from three measurements, are shown in Fig. 1. The dotted theoretical curves fit the experimental, continuous curves. The theoretical curves of the absorption edges were obtained on the assumption Card 114,1 Fine structure of X-ray... 28729 S/020/61/140/003/008/020 BI04/B125 that the metal atoms inthe octahedral neighborhood change gradually during the transition from pure nitride to pure carbide, and that one metalloid is statistically replaced by the other. This process is accompaniedonly by a slight change of the lattice constant (about 3%) and a monotonic diminution of the carrier concentration. The authors think that the 3d conduction band of the metal in carbides and nitrides is little filled. The donor-acceptor interaction of the 3d electrons of titanium with the conduction electrons of metalloidsisinsignificant. The structural changes of the K-absorption edge during the transition from pure carbide to pure nitride are monotonic (Fig.1). The structure of the absorption edge becomes more distinct with increasing carbon content in the vicinity of the titanium atoms. This fact is connected with the scattering power of metalloid atoms, The results obtained are in good agreement with those of G. V. Samsonov (Sborn. nauchn. tr, Mosk. inst. tsvetn. met. i zolota im.

The authors attempted for 'the first time to obtain di- rect information on the density of electron distribution over the energies in titanium and vanadium hydrides and to check by means of spectroscopy the hypo- thesis on the presence! of a metallic bond between metal and hydrogen atoms in bydrides. For this purpose the authors investigated the fine structure of X-ray absorption K-3pectra of titanium in hydrides with 1.2 and about 3 weight % 11, and of vanadium in hydrides with 0.12; 0.28; 0.1175; 0.75; 1.1 and 1.45 weight%H. Card 1/1 S/8119/62/0()0/000/003/016 Rcentgenospectral analysis of the.. Aoo6/AlOl Absorption edges of initial metals were also studied. To eliminate undesirable consequences of heating the specimen during the experiments, the emission spectra of Ti in hydrides of various chemical composition were analyzed with the use of the fluorescence method. All the tests were performed on a high.-intensity vacuum tube-spectrograph with Johann focusing. The titanium hydrides were prepared and analyzed by V. M. Mikheyeva, and the vanadium hydrides by T. V. Dubovik and G. V. Samsonov. The experiments proved the hypothesis on the "metallization" of the metal-hydrogen bond in the aforementioned compounds and the penetration of Is- electrons of hydrogen into the vacant 3d-band of the transition metal. This is manifested in the gradual decrease (in comparison with the metal) of intensity of the long wavelength maximum, within the range of the basic edge of the hydride absorption band, and its displacement to the short wavelength side with increas- ing hydrogen content in the hydrides until this maximum vanishes entirely. A further increase of the hydrogen content in the hydrides does not cause changes in the absorption edge structure of the metal in hydrides. As expected, the long wavelength maximum of absorption in the spectrum of the transition metal in vanadium hydrides vanishes at lesser hydrogen contents in the alloy, than in ti- tanium hydrides.

A006/A101 in the hydrides confirm fully the conclusions on the nature of the chemical bond forces In these compounds. The conclusions were drawn from the analysis of ex- perimental data on the absorption spectra of elements In these compounds. How- ever, the peculiarities of the fine structure of Ti emission bands in the hy- drides and its changes, depending on the composItIon*of the compounds, may indi- cate changes in the nature of forces of chemical interaction between hydrogen and metal in the alloys, which differ in the degree of completeness of the tran- sition metal 3d-band. It can also be considered that Is-electrons of hydrogen do not completely lose their "Individual" nature when a generalized sd-band is Lormed in the hydrides and that the effective hydrogen charge is not equal to I and can be different for hydrides rich or poor in hydrogen. This explains also the incomplete vanishing of the Kp-satellite in the emission spectra of tita- nium in the hydrides. There are 5 figures.

Absorption spectra of barium, lanthanum and cerium PERIODICAL: Zhurnal strukturnoy khimii, v. 3, no. 2, 1962, 200 - 207 TEXT: Owing to the remarkable properties of the borides of rare-earth elements'(in particular their high thermal-emission characteristics) the authors undertook a systematical investigation of the X-ray emission spectra and of the emission of metal atoms in the hexaborides of all rare-earth elements. The respectiva oxides (and the Ba compounds) were also included. The hexaborides, obtained Card 1/3 - S/192/62/003/002/002/004 The X-ray absorption spectra ... D267/D301 by reducing the respective very pure oxides with B or boron carbide, were found to contuin only the hexaboride phase. The absorption Spec- tra of metals in oxides and hexaborides were obtained with the aid of a focusing tube spectrographs in the second order of reflection from the Plane (161-1) of a bent quartz crystal. A very strong resem- blance was found to exist for the L II and L III absorption edges bet- ween the oxides and the hexaborides in the case of Ba and La, and there even exists an analogy between Ba and La. On the contrary, the curves for Ce02 differ strongly from those for CeB6, and from the curves for Ba and La compounds. The fine structure of the L absorp- tion spectra of Ba, La and Ce in oxide and hexaborides can be inter- preted quite satisfactorily as a result of superposition of contin- uous absorption and of a group ofselective lines which arise mainly due to the transition of the 2p-electrons of metals on the d-symmetry energy levels.

TITLE: Certain results of electrophysical and X-ray studies of rare earth hexaborides PERIODICAL: Fizika metallov i metallovedeniye, V-13, no-5, 1962, 744-749 TEXT: Using 12 x 1Z.5 x 0.5 mm specimens cut by spark erosion from the respective hexaborides blanks, the authors measured the following properties: specific resistivity, Hall coefficient (extrapolating for the zero porosity), thermoelectric emf, temperature coefficient of resistance, concentration of the effective current carriers nx I the mobility of current carriers um and an auxiliary quantity 6 , related to Hall coefficient (6 = R/e.' 72), expressing the magnitude of the fraction contributing to the conductivity carriers of both signs (i.e. n_u~ - n+u~). These data are summarized in a table. The electronic structure, distribution within the valency band and the magnitude of the charge on the metal were studied in sQme of these compounds by analysing the fine structure of the LI, and LIJI.

For this purpose, a focusing spectrograph was used working with the second order reflections from the 1011 of a bent quartz analyser. Dispersion within the working region was approximately 6X mm 1 and the accuracy in the determination of the energy of the se]~arate points of the fine structure absorption edges of the elements was of the order of 0.2 ev. The analysis of the absorption of the L-spectra in these compounds confirmed that the charge on the metal atom in all the rare earth hexabori'des is 3, and on the barium atom 2. A considerable shift (5 ev) was obserVed'in the LIJ absorption spectrum of Ce in CeB6, as compared with similar spectra of La or Ba, this was attributed generally to the change in the degree of screening of the terminal levels of the 2p-electrons transition in the process of L-absorption by the cerium atoms, but in the opinion of the authors this phenomenon is not fully accounted for, chierly due to the lack of further experimental data.

TITLE: Reduction of the time lag of cadmium sulfide photoresistors when weak X-ray intensities are recorded PERIODICAL: Zavodskaya laboratoriya, v. 28,.no. 5, 1962, 592-594 TEXT: The US photoresistor ~,CKM (FS7JA) is a valuable tool for recording the radiation intensity in X-ray spectroscopy and dosimetry, but for low X-ray intensities time la.-s of several minutes may occur. The resistors are fed with direct current, and the dependence of the signal-to-noise ratio on the applied voltage and the intensity of irradiation is studied. It varies _-~'rom resistor to resistor but there.is always a distinct maximum at about 20-40 volts. The reduction of the time lag by pre-irradiation with' X-rays is shown in Fig. 3. Before curve 1 was measured the resistor was kept in the dark for a lonE time.

TITLE: X-ray spectroscopic study of titanium beryllides with a high beryllium content PERIODICAL: Akademiya nauk SSSR. Dokladyp V. 142, no. 1, 1962, 85-87 TEXT: Following Ref. 1 (E. Ye. Vaynshteyn et al., DAN9 M9 642 (1960)), the authors investigated: (a) Phases of the system Ti-Be with a still higher Be content (alloys containing 88, 90, and 93 atom% of Be). (b) The data of Ref. 1 were checked and defined by increased resolving power of the spectroscopic equipment (APC (DRS) vacuum longwave spectrograph produced at the experimental workshops of the Rostovakiy gosudarstvennyy univereitet (Rostov State University)). Alloys were produced by Ye. I. Gladyshevskiy in corundum crucibles in the Tamman furnace in an argon atmosphere. Both emission and absorption spectra were taken. The reflecting (161'0) surface of a bent quartz crystal was used. The method of inclined planes was applied to magnify resolution up to 10,000 times. Emission spectra were taken with an aluminum anode. A tantalum anode was Card 1/ 5 412Y62/142/001/016/021 X-ray spectroscopic study ... B103 B11O used for the absorption spectra. The experimental form and the width of the Ka line on Ge was investigated to examine dispersion of the function of distortion caused by the parameters of the'apparatus, and to determine its half-width. It was found that the two first samples of the alloys had the same trigonal sti-acture: a - 7.40 i9 0 - 10-84 1, and c/a 1.465. This lattice is equal to that of Th 2Zn 17 (space group R 3my Z 3)1 hence, it is concluded that T12 Be 17 is produced (in accordanoe with Ref. 4, see below). It is also possiblep however# that solid solutions of TiBe 12 are involved. These two structures, being very similar to each other (as well as TiBe 2) , belong to the class of densest packages of unequally large atoms 11, with high coor---. ion numbers. The line broadening is Oo39 ev, i.e., ~ 28% of the natural half-width of the line. The form of the experimental spectm and the broadening were corrected according to I. Ya. Nikiforov (Izv. AN SSSR, ser. fiz., 21, 1362 (1957))- It was found that the shape and the relative placemer~Fof the K absorption edges and of the last emission lines in the titanium spectra of Ti-Be phases with varying Be content were almost Card 2/5 32618 8/020./62/142/001/016/021 X-ray spectroscopic study ... B103/B110 identical. The alloys investigated are yery similar with respect to atomic interaction, but differ considerably from beryllides with a lower Be content (Figs. 1, 2). This variation is a result of transitions of the K electron into the portion of the hybridized energy band of the alloy close to the 3d energy levels of the main absorption edge. It follows from the,spectra investigated; (1) a considerable weakening of the superposition degree of energy bands of valence electrons of the alloy components in T12Be 17) (Z) a ~weakening of the hybridization degree of the wave functions in the range of the 3d4sp band of the transition metall and,(3) a considerable increase in significance of the role of-Be interaction. This leads to a noticeable variation of the effective difference of eleotronegativities between the two alloy components. Its value can be estimated on the basis of X-ray spectrum data by the rela- tion between the difference (Ax) of the electronegativities of the components of a binary compound and the energy distance (AE) (KP" - K PC) in the X-ray spectrum of the transition metal. Since this value is 4.8 ev, the effective eleatronegativity of Be must differ in the . intermetallic compound from that of Ti by approximately 0.6 ev instead of Card 3/5 S/020/62/142/001/016/021 X-ray spectroscopic study B1031BI10 being practically equal.
