Correlation of the Auger electrons direction of movement with the internal electron conversion direction of movement
Abstract
On installation of coincidences of -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 (еICео-coincidences). It was established, that Auger-electrons of M-series, as well as electrons “shake-off” at -decay and internal conversion, are strongly correlated at the direction of movement with the direction of movement of basic particle (-particle, conversion electron), moving together mainly in the forward hemisphere. The intensity of correlated М-Auger radiation in range energy 1000 - 1700 eV is equal to intensity of correlated radiation “shake-off” electron from internal conversion in this range. The assumption, that the presence of spatial correlat-ing Auger-electron and conversion electron caused by current components of electron-electron interaction of particles in the final state is made.
