Description

Conditions for formation of angular and energy distributions of light particles emitted in ternary fission of 233,235U, 239Pu, and 245Cm nuclei induced by cold polarized neutrons have been studied in the course of investigating T-odd asymmetry in emission of these particles with respect to the plane formed by the fission axis and the polarization axis of the fissioning nucleus. The results obtained lead to the conclusion that in ternary fission charged particles are emitted by the fissioning nuclear system rotating around the polarization direction

Abstract (Russian)

При исследовании эффекта Т-четной асимметрии эмиссии легких частиц относительно плоскости, образованной направленеиями оси деления и поляризации делящегося ядра, изучены условия формирования их угловых и энергетических распределений в тройном делении 233U, 235U, 239Pu и 245Cm холодными поляризованными нейтронами. Полученные результаты приводят к выводу, что заряженные частицы в тройном делении испускаются делящейся ядерной системой при ее вращении вокруг направления поляризации
