Abstract

High-precision measurements are carried out on a п√2 magnetic b-spectrometer for the relative intensities of the electron lines of internal conversion on the K- and L-shells of 165Ho nucleus, with the 362-keV y-transition being used. The penetration parameter л for the M2-component of this transition and the multipole mixing ratio б(E3/M2) are determined for the first time. The value of E3-multipolarity admixture corresponds to the probability of radiative transition B(E3)(362 keV)=(46±6) W.u., which testifies to its collective nature and a probable octupole deformation of 165Ho nucleus.
