Abstract

High-spin states in 197Pb have been investigated by in-beam γ-ray spectroscopy. Two previously known high-spin magnetic-dipole sequences have been connected to the spherical level scheme at lower spins. A reordering of the transitions in the previously reported irregular band leads to a regular sequence with a band crossing. The properties of the dipole sequences are interpreted in terms of “shears bands” within the tilted-axis cranking model.
