T,T,'XT: The )jI.-spectra in the energy range from 0-4 to 9-5 Mov were measured
in a magnetic Compton sp ectrometer giving a resolution of 0.3F~ for energie s

(Izv. AN 353R. Ser. fiz -1-2 , 791 (1960)). The spectrum of internal'con-

132 lines were resolved, containing 37% of the total energy released by the
neutron capture. To measure the internal conversion spectrum a cadmium
oxide target of 0.8 mg/CM2.thickness,.enriched to 85% Cd113 on an aluminum
backine foil was used. This spectrum contained 36 lines up to energies o~
1.7 Mev. The energies, relative intensities, and internal 6onversion
coefficients of the lines were tabulated. From these data, a level scheme
f was constructed assuming that the relatively intense lines with energies
above 5 14,ev,correspond to transitions from the initial state formed by the
neutron capture to the lower nuclear levels. The binding energy of the

TEXT: Thermal neutron capture gamma rays can,in certain circumstances.be
used for quantitative determination of rare-earth impurities, provided a
magnetic Compton spectrometer of high resolution is available. The
impurities to be determined must have large, and the substance in which
they are contained, small, cf,, an d Bn values. anis the thermal neutron
capture cross section and B is the binding energy of the last neutron.

The method was tested by determining Sm and Gd impurities in other
rare-earth substances. The minimum concentrations which can be determined
with a Compton r-spectrometer of 2 % resolution are given in the table,
The 6.74- and 7.22-Mev.lines, which are charac~~ristio of Gd and Sm, have
