Microscopic description of excitation of nuclear isoscalar giant resonances by inelastic scattering of 240 MeV particles -: art. no. 034312 Academic Article uri icon


  • A microscopic description of the excitation of isoscalar giant monopole resonance (ISGMR) and quadrupole resonance (ISGQR) in [Formula Presented] [Formula Presented] and [Formula Presented] by 240 MeV bombarding energy [Formula Presented] particles is provided based on self-consistent Hartree-Fock (HF-) random-phase-approximation (RPA) approach and the distorted-wave Born approximation (DWBA). The folding model is used to obtain optical potentials from the HF ground-state density and a density dependent Gaussian nucleon-[Formula Presented] interaction [Formula Presented] The parameters of [Formula Presented] are determined by fitting experimentally measured angular distributions for the case of elastic scattering. Angular distributions of inelastically scattered [Formula Presented] particles for ISGMR and ISGQR excitations of the target nucleus are obtained using the folding model DWBA and both microscopic (RPA) and hydrodynamical (collective model) transition densities (found from HF ground state densities). A possible overestimation of the energy weighted sum rules and shifts of centroid energies due to the collective-model-based DWBA reaction description is reported. 2000 The American Physical Society.
