Abstract

The nucleus Pb-197 was populated via the W-186(O-17, 6n) Pb-197 reaction at beam energies of 98 and 110 MeV. Two regular DELTA-I=1 bands of magnetic dipole transitions have been found. Possible interpretations in terms of collective oblate configurations involving high-K proton orbitals coupled to three i13/2 neutrons are discussed. The similarities between several of the bands discovered in Pb-197-200 nuclei are emphasized.
