Semiclassical model of dipole Pygmy-resonance in nuclei with neutron excess
Description
To study the dipole pygmy-resomanace in nuclei with neutron excess, it is proposed to use a semiclassical model based on the dynamics in the phase space. The properties of the neutron skin of a nucleus are presented by a surface layer of moving neutrons. It is obtained that the strength function of the spherical layer has a resonance with the maximum energy corresponding to the energy of the dipole pygmi-resonance observed in the 208 Pb nucleus.
