Description

Precise measurement of 241Am decay γ-spectra has been performed.New intensity values for some Lx-lines were obtained with accuracy approx 1%. For 237U decay natural width of Ka-lines was taken into account when calculating aK=2.53 ± 0.03.This corresponds to penetration effects with parameter λ=0.26 ± 0.14.For the first time γ-radiation of M4-transition with E=30.8 keV at 93m Nb decay was observed and aK=(2.42 ± 0.09) centre dot 104 was obtained. Also satellite γ-line with E=28.4 keV corresponding to non-elastic 'electron bridge' was observed. Relative probability of this process PEB/Pγ=(6.1 ± 1.4) centre dot 10-2 was calculated
