Isotopic Study of Nh Element in Reference to the Heavy Particle Radioactivity

Abstract

Preformed cluster model is applied to examine the ground state decay of various even isotopes of Z = 113 (Nh) parent nucleus with A = 278–292. Within the Skyrme energy density formalism, SVand SAMi Skyrme forces are used to identify the probable clusters from the considered emitters by investigating the fragment (cluster) mass yield (or cluster formation probability P₀). The calculations suggest that, for ^278–292113 parent nuclei, the maxima at cluster region arises due to the shell closure effects around neutron magic number N = 50. However, with the increase in mass of the emitter, the magicity of daughter also start to appear around N = 126.
