Fusion and Fission from Time-dependent Hartree-Fock

Paul D. Stevenson, University of Surrey, United Kingdom
Physics Division, Bldg. 6008 Large Conference Room

Fusion and fission are large-amplitude processes in atomic nuclei. Working at the level of the time-dependent mean-field allows for a starting point for studying the microscopic dynamics in such processes. We present calculations of fusion reaction cross-sections, to assess the sensitivity of the cross-section to nuclear matter properties, via the neutron skin in 48Ca. In the case of fission, TDHF can only model induced fission, since tunnelling of collective coordinates is not available. We present some calculations of induced fission in 240Pu, using either collective boosts or large initial deformations to follow the dynamics as energy is transferred from potential energy into the collective motion and excitation of the daughter fragments.
