Trajectory calculations for light-particles emitted in spontaneous ternary fission

Abstract

Trajectory calculations have been carried out for 252Cf fission accompanied by 1H, 2H, 3H, 6He and 8He particles. Initial dynamic variables of the fissioning system were found which gave satisfactory fits to the observed energy spectra. It was found that the heavy fragment separation at scission increases as the mass of the third particle decreases. The energy cost in releasing each of the particles was calculated and three factors influencing the fractional yields were identified.
