Abstract: Measurements of energy spectrum of "shake-off" electrons in the decay of 152Eu and their correlations relatively to outgoing direction with a momentum of β-particle are conducted. The measurements are performed in the range of 150 - 2000 eV on the installation of coincidences of γ-quanta and β-particles with low energy electrons, including е0-electrons of the secondary electron emission (γβе0-coincidences). Registration of "shake-off" electrons was implemented on е0-electrons, created by them. Under the obtained data 70% of "shake-off" electrons in the measured part of the spectrum is arranged up to 500 eV, and "shake-off" electrons are heavily correlated relatively to outgoing direction with a β-particle, herein their correlation with the energy of "shake-off" electron is increasing, qualitatively subjected to ∼ Е1/2 relation.

Keywords: electrons of "shake-off", β-decay, 152Eu.
