Symmetry Energy, Pairing Correlations and Giant Resonances in Tin Isotopes

초록

We investigated isoscalar giant monopole resonances (GMRs) and isovector giant dipole resonances (GDRs) in tin (Sn) isotopes to study the symmetry energy in the low density region by using the quasi-particle random phase approximation (QRPA). Centroid energies for the giant resonances were derived from corresponding transition amplitude strength distributions and compared to the available data. The changes in the centroid energies of the resonances in the Sn isotopes are discussed in detail with the incompressibility.
