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…
