Abstract: Angular distribution of low energy electrons from 152Eu decay was measured. Measurements were carried out in cylindrical geometry, which permits minimum distortions of data. These data confirm existence of angular distribution dependence on the energy of emitted electrons but this dependence somewhat differs from theory predicted. It is noted that the theory predicts too low intensity of near-zero energy electrons e0 (Ee ~ 1 - 2 eV) emission; also, the static screening of charge used in theory should not influence the emission of e0-electrons.

Keywords: 152Eu decay, low energy electrons, angular distribution.
