Contribution

It introduces the use of density constrained TDHF to directly compute fusion barriers and includes dynamical Coulomb excitation effects for the first time in this context.

Findings

Fusion cross sections agree well with experimental data.

Dynamical Coulomb excitation influences fusion barrier heights.

Particle transfer impacts fusion probability.

Abstract

We study fusion reactions of the $^{64}$Ni+$^{132}$Sn system using the recently introduced density constrained time-dependent Hartree-Fock formalism. In this formalism the fusion barriers are directly obtained from TDHF dynamics. In addition, we incorporate the entrance channel alignment of the deformed (oblate) $^{64}$Ni nucleus due to dynamical Coulomb excitation. We discuss the influence of particle transfer and other dynamical effects on the fusion cross sections. Calculated cross sections are in very good agreement with data and other calculations.
