Two-body dissipation effects on synthesis of superheavy elements

Nuclear Theory 2016-03-23 v1

Abstract

To investigate the two-body dissipation effects on the synthesis of superheavy elements, we calculate low-energy collisions of the N=50N=50 isotones (82^{82}Ge, 84^{84}Se, 86^{86}Kr and 88^{88}Sr) on 208^{208}Pb using the time-dependent density-matrix theory (TDDM). TDDM is an extension of the time-dependent Hartree-Fock (TDHF) theory and can determine the time evolution of one-body and two-body density matrices. Thus TDDM describes both one-body and two-body dissipation of collective energies. It is shown that the two-body dissipation may increase fusion cross sections and enhance the synthesis of superheavy elements.
