considered on these corrections. Compooite linen are separated into singu-
lar components with the help of standard lines., The results obtained agree
well with data given in Refs. 3 and 5, but differ very much from those
given in Refs. 4 and 6. The hard region of the spectrum was investigated
by means of a ritron. After the corrertione had been introduced, the interk-
sities of the hard lines were determined (Table). The resolution of the
ritron, however, was not high enough to separate the gamma linen, as was
done in Refs. 1 and 2. Therefore, the intensities of the hard lines deter-
mined with standard lines are not as accurately given as those in Refs, 1
and 2. Special attention had been paid to investigate the spectral region
around 1,600 kev. It was found that in this region the number of coinci-
dences does hardly exceed the background. The reaul~s of the study showed
that if 1608.5-kev gamma quanta exist, their maximum intensity amounts to
0.054/v of the 1121.6-kev line intensity. There are 3 figures, 1 table, and
10 references: 5 Soviet-bloc.
