Temperature dependent study of neutron-rich thermally fissile 244−262Th and 246−264U nuclei within E-TRMF model
Abstract We have studied the fission parameters of hot neutron-rich thermally fissile T 244 − 262 h and U 246 − 264 nuclei within the temperature dependent effective field theory motivated relativistic mean field (E-TRMF) formalism by using the recently developed FSUGarnet and IOPB-I parameter sets. The results obtained by these two forces are compared with the results of the well known and widely accepted NL3 parameter set. The excitation energy E ⁎ , shell correction energy δ E s h e l l , single particle energy for neutrons and protons ϵ n , p , level density parameter a , neutron skin thickness Δ R , two neutron separation energy S 2 n , and asymmetry energy coefficient a s y m of these neutron-rich thermally fissile nuclei are calculated at finite temperature. The dependency of level density parameter and other observables on the temperature and the force parameters (interaction Lagrangian) are discussed.
