Abstract
The nucleus 197 Pb was populated via the 186 W( 17 O,6n)197 Pb reaction at beam energies of 98 and 110 MeV. Two regular ΔI=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 i 13/2 neutrons are discussed. The similarities between several of the bands discovered in 197–200pbnuclei are emphasized.
