Configuration transition effect in heavy-ion fusion reactions with deformed nuclei

Abstract

Fusion reactions of 16O + 24Mg are investigated with the three-dimensional time-dependent Hartree-Fock (TDHF) method. The resultant fusion excitation functions show some novel features that are beyond the current understandings and the predictions of various theoretical models. We will demonstrate that these phenomena cannot be explained by a density rearrangement effect but by the configuration transition mechanism in the dynamical process.
