Isoscalar giant resonances for nuclei with mass between 56 and 60
Abstract
The giant resonance region from 10 MeV < E-x < 62 MeV in Fe-56, Ni-58, and Ni-60 has been studied with inelastic scattering of 240 MeV alpha particles at small angles, including 0 degrees. Most of the expected isoscalar E0 and E2 strength has been identified below E-x = 40 MeV. Between 56 and 72% of the isoscalar E1 strength has been located in these nuclei. The mass dependence of the giant monopole energy between A = 40 and 90 is compared to relativistic and nonrelativistic calculations for interactions with compressibility of nuclear matter K-NM similar to 211-225 MeV.
