Spectrometer for determination of internal conversion of gamma-rays
	S. V. Chenmarev

In this paper we used a spectrometer optimized for measurements of ICC on the basis of semiconductor high purity germanium detector with a thin beryllium entrance window, which allows registration of X-rays, gamma-rays and electrons.
Measurement of a total gamma and beta spectra and pure gamma-ray spectra without  electrons, with cut-off with an aluminum filter in front of the entrance window was carried out.
As a result of the experiments, data were obtained, from which we calculated internal conversion coefficients αK and K/L for the transition of 661 keV Cs-137, αK in 121.8 keV transition in Eu-152 and αL  on 59.5 keV transition in Am-241.
The obtained values ​​within the error limits correspond to the theoretical values ​​of the ICC is nice-to-energy conversion of data and multipolyties for the corresponding charges of the daughter nuclei, the values ​​given in the table from L. A.  Sliv.
