Abstract
Inelastic scattering of 480 MeV and 340 MeV α particles on 208Pb, 116Sn and 58Ni has been used in a search for high excitation energy giant multipole resonances, up to E* = 60 MeV for 208Pb and E* = 45 MeV for 116Sn and 58Ni. Above the well known quadrupole and monopole resonances, there is clear evidence for a very wide set of negative parity modes (including the already known high energy octupole), followed and mixed with another very wide set of positive parity resonances, extending up to the limits of the experimental spectra.
