Non-local kinetic simulation of heavy ion collisions
Klaus Morawetz
The numerical solutions of nonlocal and local Boltzmann kinetic equations for the simulation of peripheral and central heavy ion reactions are compared. The experimental finding of…
Collective modes in asymmetric nuclei
Klaus Morawetz, Uwe Fuhrmann, Rainer Walke
The collective motion of a finite nuclear system is investigated by numerical simulation and by linear response theory. Using a pseudo-particle simulation technique we analyze the…
ISGDR- bulk or surface mode ?
Klaus Morawetz, Uwe Fuhrmann
A polarization and response function for finite systems and temperatures is derived from linearizing the Vlasov equation. Besides the Lindhard response function in local density ap…
Damping of IVGDR - Fermi-liquid or Fermi-gas ?
Klaus Morawetz, Uwe Fuhrmann
Collisional relaxation rates of collective modes in nuclei are calculated using the Levinson equation for the reduced density matrix with a memory dependent collision term. Lineari…
Space-time versus particle-hole symmetry of collisions in a non-local kinetic equation for dense Fermi systems
Václav Špička, Pavel Lipavský, Klaus Morawetz
Binary collisions in Fermi systems obey two fundamental symmetries corresponding to the space and time inversion and to the interchange of particles and holes. We show that beyond…
Simulation of Heavy Ion Reactions with Nonlocal Kinetic Equations
K. Morawetz, V. Špička, P. Lipavský +1
The incorporation of realistic trajectories of two-particle scattering into existing BUU or QMD codes meets considerable difficulties. We propose a method of replacing the scatteri…
