Description
The mechanism underlying the emission of light charged particles (LCP) with Z = 1, 2 from fragments produced in fission of uranium nuclei by 153 MeV protons and 1700 MeV negative pions was studied. It was found that LCP accompanying the fission by pions are emitted from non-accelerated fragments immediately after the fission, whereas in the case of 153 MeV protons, the LCP are emitted from the accelerated heavy fragments. The number of LCP emitted in the course of pion-induced fission is 0.7 per fission event, which exceeds by a factor of 30 the corresponding number for 153 MeV protons
Abstract (Russian)
Изучается механизм лежащий в основе эмиссии легких заряженных частиц (ЛЗЧ) с Z = 1, 2 из фрагментов, рожденных в делении ядер урана протонами с энергией 153 МэВ и отрицательными пионами с 1700 МэВ. Было найдено, что ЛЗЧ, сопровождающие деление пионов эмиттируют из неускоренных фрагментов немедленно за делением в случае 153 МэВ протонов, ЛЗЧ эмиттируют из ускоренных тяжелых фрагментов. Число ЛЗЧ эмиттированных в течение деления, вызванного пионами есть 0,7 на каждое событие деления, которые превышают фактор 30 соответствующего числа для 153 МэВ протоновFiles
