The relation of energy of autoionization electrons and them correlating on an outgoing direction with a beta-particle from boundary energy of brta-particle is investigated. The measurements are executed on the installation of coincidences of gamma-quanta and beta-particle with law energy electrons at registration of autionization electrons by eo-electrons a secondary electron emission (gamma beta eo-coincidences), created by them. Under the obtained data the expansion of a energy spectrum of autoionization electrons is proportional to boundary energy of beta-spectrum. The correlating direction of emitting of autoionization electron on outgoing directions of beta-particle does not depend on energy beta-particle. On installation of coincidences of gamma-quanta with electrons and with law energy electrons about zero area the spatial correlation of the direction emitting Auger-electrons and electron of internal conversion was investigated at the 152Eu decay. Auger-electrons were registered on ео-electrons of the secondary electron emission (gamma еIC ео-coincidences). Was established, that Auger-electrons of M-series, as well as electrons "shake-off" at beta-decay and internal conversion, are strongly correlated at the direction of movement with direction movement of basic particle (beta-particle, conversion electron), moving together with it mainly in the forward hemisphere. The intensity of correlated М-Auger radiation in a range energy 1000 - 1700 eV is equal to intensity of correlated radiation "shake-off" electron from internal conversion in this range. The assumption is made, that the presence of spatial correlating Auger-electron and conversion electron caused by current components of electron-electron interaction of particles in the final state. On installation of coincidences of gamma-quanta with electrons and with law energy electrons about zero area the spatial correlation of the direction emitting accompanying eas particles (electron "shake-off", Auger electron) with respect to the primary particle em (electron) at beta-decay or internal conversion of transitions in 152Eu decay have been investigated. By measuring the double- gamma eac and triple gamma eac em-coincidences the correlating movement of the accompanying particle and the main particle in the same hemisphere emission and in opposite hemispheres emission were measured. It was received that, in first case the correlating >> 1, and, in other case correlating << 1. It is discussed the mechanism of strong spatial correlation in the motion of accompanying particle with the main particle in the process of radioactive decay and internal conversion for the account the current components of the electron-electron interaction in the final state particles. Correlation study the motion of "shake-off" electron (as accompanying particle) with positron (as main particle) on installation for measure double, triple, fourth coincidences gamma-quanta with beta- -particles, electrons and with law energy electrons, including eo-electron of the secondary electron emission, have been performed for 152Eu decay. Correlation electron "shake-off" with positron are measured concerning correlation electron "shake-off" with beta- -particle on the base carrying out the measurements gamma, gamma beta, gamma (ео+ beta)-, gamma beta ео- and gamma beta gamma511-, gamma beta gamma511 ео-spectra. It was established, that accompanying particle (electron "shake-off") are strong correlated in forward with the main particle (beta- -particle), it being correlation motion with positron in 1.6 times greater correlation motion with beta- -particle and make up 5.2(20) at the measurement in 152Eu decay. The possible qualitative mechanism of strong correlation motion the accompanying particle with the main in beta-decay processes and internal conversion, as caused current components of direct interaction particle, is discussed.
