AbstractThe energy density functional view of nuclei provides a good description of ground state properites and is linked to the underlying nuclear interactions via the Hartree-Fock (HF) approximation. The extension of HF to dynamical processes via the time-depdendent HF approach allows description of collective nuclear behaviour, including giant resonances and collisions.
We present a survey of some recent results with time-dependent approaches; Various properties of giant-resnonace-like modes are explored, including low-lying dipole strength in Se-76 , in which a non-multipole excitation is used to pick out "pygmy" strength; Some technical advances leading to a true continuum theory ; Results n giant resonances and fusion from exploring tensor terms in the nuclear interaction [3,4].
Some details of a newly-published code allowing such calculations to be performed will also be presented .
