Breathing mode in an improved transport approach — •Theodoros Gaitanos, Alexei Larionov, Horst Lenske, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen

The nuclear breathing-mode giant monopole resonance is studied within an improved relativistic Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) transport approach. As a new feature, the numerical treatment of ground-state nuclei and their phase-space evolution is realized with the same semiclassical energy-density functional. With this new method a very good stability of ground-state nuclei in BUU simulations is achieved. This is important in extracting clear breathing-mode signals for the excitation energy and, in particular, for the lifetime from transport theoretical studies including mean-field and collisional effects.
