Internal-conversion electrons from 122- and 136-keV γ transitions in 57Fe

The spectra of internal-conversion electrons from the 122- and 136-keV γ transitions in 57Fe are studied by using a double-focusing magnetic β spectrometer of the section type. The ratios of the intensities of conversion electrons are determined for K and L shells and for LI, LII, and LIII subshells, and conversion coefficients are found for LI, LII, and LIII subshells. The multipolarities of the γ transitions under study are established, and relative admixtures in these transitions are determined
