Three-dimensional time-dependent Hartree-Fock calculations of 16O + 16O and 40Ca + 40Ca fusion cross sections

Three-dimensional time-dependent Hartree-Fock calculations for the 16O + 16O and 40Ca + 40Ca fusion excitation functions are presented. Results for the former system are in good agreement with experiment for Elab≤120 MeV and indicate a dynamical lower angular momentum limit to fusion for Elab≥54 MeV. Results for 40Ca + 40Ca are compared with previous two-dimensional calculations. The low-energy fusion cross sections obtained for this system demonstrate the sensitivity of time-dependent Hartree-Fock calculations to the effective interaction used.
