Phys. Rev. C 73, 014314 (2006) [10 pages]Isoscalar giant resonances for nuclei with mass between 56 and 60Received 19 October 2005; published 26 January 2006 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. © 2006 The American Physical Society URL:
