Relativistic nuclear excitation—A new approach

Nuclear Matter and Nuclear Dynamics

“…In Ref. [28] a relativistic treatment is elaborated, to derive the equations of motion of (projectile and target) neutron and proton centroids, under the action of the restoring isovector nuclear force, taking into account in the excitation of the dipole oscillations, apart from Coulomb effects, also the contribution of the nuclear potential, treated with a Wood-Saxon potential well. It is observed that mean-field effects give a strong contribution to the excitation of the dipole oscillation, that is connected to the neutron skin of the target nucleus, leading to a different attraction between the target protons or neutrons and the projectile nucleons.…”
