M. Mirea et al., KR AND XE NEUTRON-RICH NUCLEI PRODUCTION THROUGH U-239 FISSION, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 111(3), 1998, pp. 267-280
The theoretical formalism and some results of a model realised for fis
sion processes in a wide range of mass asymmetries are presented. The
fission barriers are computed in a tridimensional configuration space
using the Yukawa-plus-exponential macroscopic energies corrected withi
n the Strutinsky procedure. It is assumed that channel probabilities a
re proportional with Gamow penetrabilities. The model is applied for t
he disintegration of the U-239 in order to determine the relative yiel
ds for the production of neutron-rich nuclei at diverse intermediate e
nergies. An analysis of the experimental data obtained in the framewor
k of the PARRNE project is reported.
