Dynamical Cluster-decay Model Based on Skyrme Force KDE0(v1) and the Dynamics of 208,206,204Pb+48Ca →256,254,252No? Reaction

摘要

Extending our earlier work on 48Ca + 204;206;208Pb reactions, based onthe Dynamical Cluster-decay Model (DCM) using the pocket formula fornuclear proximity potential, we study the cross sections xn for the decayof the compound nuclei 252;254;256No , synthesized in 48Ca + 204;206;208Pbfusion reactions, via 1n–4n evaporation channels. For this study, we usethe DCM with the Skyrme force KDE0(v1). Deformations 2i and hotoptimumorientations i at various excitation energies E from 19.6 to43.6 MeV are included. Interestingly, for the use of a Skyrme force, theDCM reproduces the data very well with one parameter R fitted to themeasured data on fusion evaporation residues (ER).
