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…
Giant Octupole Resonance Simulation
Rainer Walke, Klaus Morawetz
Using a pseudo-particle technique we simulate large-amplitude isoscalar giant octupole excitations in a finite nuclear system. Dependent on the initial conditions we observe either…
Damping of giant resonances in asymmetric nuclear matter
K. Morawetz, U. Fuhrmann, R. Walke
The giant collective modes in asymmetric nuclear matter are investigated within a dynamic relaxation time approximation. We derive a coupled dispersion relation and show that two s…
Consequences of coarse grained Vlasov equations
Klaus Morawetz, Rainer Walke
The Vlasov equation is analyzed for coarse grained distributions resembling a finite width of test-particles as used in numerical implementations. It is shown that this coarse grai…
New collective mode due to collisional coupling
K. Morawetz, R. Walke, U. Fuhrmann
Starting from a nonmarkovian conserving relaxation time approximation for collisions we derive coupled dispersion relations for asymmetric nuclear matter. The isovector and isoscal…
Damping rates of hot Giant Dipole Resonances
U. Fuhrmann, K. Morawetz, R. Walke
The damping rate of hot giant dipole resonances (GDR) is investigated. Besides Landau damping we consider collisions and density fluctuations as contributions to the damping of GDR…
