Giant resonances in Sn-112 and Sn-124: Isotopic dependence of monopole resonance energies

Abstract

The giant resonance region from 10 MeV <E-x< 55 MeV in Sn-112 and Sn-124 has been studied with inelastic scattering of 240 MeV ? particles at small angles including 0andDEG

. Essentially, all of the expected isoscalar E0-E3 strength was located in both nuclei. The isotopic dependence of the giant monopole resonance energies was found to be consistent with relativistic and nonrelativistic calculations for interactions with K-NM andSIM

220-240 MeV.
