Determination of neutron-induced fission fragment spin distribution after neutron evaporation
Abstract : Nuclear fission consists of splitting a nucleus into smaller nuclei. Several observables
are available to study the fission process such as fission yields or
fission fragment angular momentum. Currently, fission models cannot predict
all the observables with an acceptable accuracy for nuclear fuel cycle
studies for instance. Improvement of fission models is an important issue for
the knowledge of the process itself and for the applications. In this work, we
take an interest in fission fragment angular momentum distribution. Isomeric
ratios (IRs) are a common observable giving access to investigate these distributions.
We measured accurate IRs for 88Br, 132Sn and 132Te with the fission
fragment separator LOHENGRIN and developed a new analysis method to
assess the mean value and uncertainty of the IR. An evaluation of the angular
momentum distribution of 132Sn was also performed with the FIFFRELIN
code.
