Combining a langevin description of heavy-ion induced fission including neutron evaporation with the statistical model

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

A model is developed which combines dynamical (Langevin-) calculations with the Kramers modified statistical model in order to describe heavy-ion induced fission including neutron evaporation. In the example of the19F+181Ta collision, the energy dependence of fission probabilities, neutron multiplicities and (H.I.,xn)-cross sections is calculated and a fair agreement with the data is achieved with a reduced friction parameter ofβ=3*1021sec−1. We pay particular attention to the angular momentum dependence of the fusion-fission process.
