Analysis of fragment angular distributions from heavy - ion reaction

Abstract

Statistical scission model is applied to fission fragment angular distributions from heavy-ion induced Fission. Comparison of model calculations to experimental data on angular distributions for 11B, 12C and 14N on 209Bi system shows excellent agreement. It is shown that statistical scission model (SSM) predicts angular distributions in reasonable agreement with those measured for heavy-ion induced fission of some reaction systems where the fission barrier has vanished or is very small relative to the nuclear temperature. © 2014 Atomic Energy Society of Japan.
