Analysis of Fragment Angular Distributions from Heavy - Ion Reaction

摘要

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 ~(11)B, ~(12)C and ~(14)N on ~(209)Bi 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.
