Description
The spreading width of nuclear giant dipole resonance in Pb208 is studied in the Boltzmann-Uehling-Uhlenbeck transport theory with a lattice Hamiltonian method.
The obtained spreading width shows a strong dependence on the in-medium nucleon-nucleon elastic scattering cross sections, which suggests the spreading width of nuclear giant dipole resonance as a novel probe of the medium correction of the nucleon-nucleon elastic scattering cross sections. We then find that the experimental value of giant dipole resonance width of Pb208 measured at RCNP prefers a strong medium effects.
