Abstract: The study of autoionization of atomic shell at β-decay of 152Eu was performed. Relation of energy of autoionization electrons and their correlation on outgoing direction with a β-particle from boundary energy of β-particle was investigated. Measurements are executed on the installation of coincidences of γ-quanta and β-particle with low energy electrons at registration of autionization electrons created by e0-electrons of the secondary electron emission (γβe0-coincidences). Due to obtained data the expansion of a energy spectrum of autoionization electrons is proportional to boundary energy of β-spectrum. Correlation direction of emitting of autoionization electron on outgoing directions of β-particle does not depend on energy of β-particle.

Keywords: autoionization electrons, β-decay, 152Eu.
