Microscopic study of O+O fusion
arXiv:1306.5514 · doi:10.1103/PhysRevC.88.024617
Abstract
We perform a study of O+O fusion at above and below the interaction barrier energies using three-dimensional time-dependent Hartree-Fock (TDHF) calculations at above barrier energies and density-constrained TDHF calculations for the entire energy range. We discuss the variations of the experimental data at above the barrier energies. Calculations reasonably reproduce the observed energy-dependent broad oscillations in the fusion excitation functions. These oscillations result from overcoming -dependent fusion barriers. The role of the coupling to low-lying octupole states is also discussed.
