Abstract

We report the results of an experiment, realized with the EUROBALL IV spectrometer, in which superdeformed (SD) states have been populated in ^197,198Pb nuclei. Crosstalk transitions between two signature partner SD bands in ¹⁹⁷pb have been observed with an established M1 character, giving access to the magnetic properties of the v[752]5/2 intruder orbital. Six new SD bands have been identified in ^197,198Pb. The results are interpreted in the framework of cranked Hartree-Fock calculations. A mixing between quasi-particle excitations and an octupole vibration is suggested in the two SD isotopes.
