An extended Vlasov equation with pairing correlations
V. I. Abrosimov, D. M. Brink, A. Dellafiore +1
A simplified version of the Wigner--transformed time--dependent Hartree--Fock--Bogoliubov equations, leading to a solvable model for finite systems of fermions with pairing correla…
Octupole response and stability of spherical shape in heavy nuclei
V. I. Abrosimov, O. I. Davidovskaya, A. Dellafiore +1
The isoscalar octupole response of a heavy spherical nucleus is analyzed in a semiclassical model based on the linearized Vlasov equation. The octupole strength function is evaluat…
Effects of surface vibrations on quadrupole response of nuclei
V. I. Abrosimov, A. Dellafiore, F. Matera
The effect of quadrupole-type surface vibrations on the quadrupole response function of heavy nuclei is studied by using a model based on the solution of the linearized Vlasov equa…
Oscillations in finite Fermi systems
V. I. Abrosimov, A. Dellafiore, F. Matera
A semiclassical linear response theory based on the Vlasov equation is reviewed. The approach discussed here differs from the classical one of Vlasov and Landau for the fact that t…
