Yrast and near-yrast spectroscopy of neutron-rich fission fragments using thermal neutrons from reactor

The spectroscopic studies of fission fragments provide direct information on the nuclear excited states, which are related to the shape and structure of the neutron-rich fragment nuclei. Thermal neutron induced fission is one of the techniques which allows us to do spectroscopic investigation of such fragment nuclei with a higher neutron to proton ratio. These types of studies help to explore the new regions of nuclear deformations, and to extend the theoretical model(s) to regions which have hitherto been inaccessible. Here a comparative study in terms of yrast and near-yrast spectroscopy of the neutron-rich fragments that were produced in the thermal neutron induced fission of 235U have been reported
