Study of Decay Properties of 260 Sg* Nucleus Formed in 52 Cr + 208 Pb Reaction by Using GSkI Skyrme Force

The excitation functions of 260 Sg* studied on the basis of the Dynamical Cluster-decay Model (DCM). For the nuclear interaction potentials, we use the Skyrme energy density functional (SEDF) based on semiclassical extended Thomas Fermi (ETF) approach under frozen density approximation. The Skyrme force used is the new GSkI force for our calculation for cross section and comparison with the experimental data. Here, only the EFs for the production of 260 Sg* isotope via 2 n decay channel from the 260 Sg* compound nucleus are studied at E *= 13.3 to 18.6 MeV, including quadrupole deformations β_2i and “cold-optimum” orientations θ_i . The calculations are made within the DCM where the neck-length Δ R is the only parameter representing the relative separation distance between two fragments and /or clusters A i ( i = 1, 2) which assimilates the neck formation effects.
