Isoscalar giant resonances for nuclei with mass between 56 and 60

The giant resonance region from 10 MeV <Eₓ<62 MeV in ⁵⁶Fe, ⁵⁸Ni, and ⁶⁰Ni 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~211--225 MeV.
