Abstract
We develope a method to evaluate large amplitude time-dependent Hartree-Fock (TDHF) dynamics in a single mode and in the presence of a thermal barh. We first apply the method with realistic interactions in the small oscillation regime to isothermal and isentropic breathing mode oscillations. We present the coefficients for the T = 0 incompressibilities and breathing mode frequencoes for 16O and 40Ca. We obtain a significant effect on the collective mass due to the non-locality of the realistic effective interaction. The consequence is that the interaction produces a remarkably low value for the incompressibility while providing an adequate description of the breathing mode energy. We conclude that nuclear matter may have an incompressibility significantly lower than 200 MeV. We present initial results for large amplitude static compression of 40Ca at T = 0 which include the excitation of nucleons to deltas.
