Description

Currently, reaction measurements on fission products are being planned by the Nuclear Science PG at both Argonne Nat. Lab and at FRIB (Facility for Rare Isotopes, Michigan State). These indirect experiments produce specific short-lived nuclei via beta decay, and the subsequent neutron and gamma emission are studied. Some initial experiments found a surprising overabundance of gamma emission. Two possible explanations are 1) an inadequate description of states populated in beta-decay and 2) an enhanced gamma-ray strength function (related to the gamma emission probability). Resolving the issue is of broad importance and requires theoretical development. We are developing an integrated nuclear data workflow that connects advanced nuclear shell model codes for describing the beta decay in these experiments with a contemporary nuclear reaction model code.
