Medium-dependent relativistic NN potential: Application to fusion dynamics

In-medium effects are introduced in the microscopic description of the effective nucleon-nucleon (NN) interaction potential entitled DDR3Y in terms of the density-dependent nucleon-meson couplings within the relativistic-Hartree-Bogoliubov (RHB) approach. The nuclear densities of the interacting tar...

description In-medium effects are introduced in the microscopic description of the effective nucleon-nucleon (NN) interaction potential entitled DDR3Y in terms of the density-dependent nucleon-meson couplings within the relativistic-Hartree-Bogoliubov (RHB) approach.
