M1 scissors mode for gamma emission spectrum and its effect

Up to now, the anomalous bumps which appear in low energy gamma have been described by introducing the E1 pygmy resonance. But this method has difficulty to describe the bumps, which appear in the rare earth and actinide nuclei, because they are deformed. In order to obtain the spectra for such deformed nuclei, we have to consider another kind of electromagnetic transition, M1 scissors mode excitation. By adding M1 scissors mode as well as E1 pygmy resonance into giant multipole resonance for Gd and U isotopes, which have the experimental data, and analyzing with the Hauser-Feshbach statistical model, we obtained improved gamma emission spectra
