Abstract

The giant resonance region from 10 MeV <Ex<62 MeV in Fe56, Ni58, and Ni60 has been studied with inelastic scattering of 240 MeV α particles at small angles, including 0°. Most of the expected isoscalar E0 and E2 strength has been identified below Ex=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 KNM~211225 MeV.
