Abstract

The preliminary experimental data on the spectrum of internal-conversion electrons of the erbium fraction in the range of electron energies near ∼140 keV are reported. A photographic plate with a spectrogram of erbium fraction, exposed on the spectrometer of the Laboratory of Nuclear Problems (Joint Institute for Nuclear Research), was then measured on the PAVIKOM-1 microscopic complex (Lebedev Physical Institute). Due to the large number of spectral lines in this region, it was previously impossible to determine the intensities of the L 2 and L 3 lines of internal-conversion electrons for the 148.16-keV transition in the 161Ho nucleus. The use of the PAVIKOM-1 microscopic complex with a resolution of 0.01% made it possible to identify these lines and determine their intensities.
