Abstract
High-spin states in (197)pb have been investigated by in-beam gamma-ra y spectroscopy. Two previously known high-spin magnetic-dipole sequenc es have been connected to the spherical level scheme at lower spins. A reordering of the transitions in the previously reported irregular ba nd leads to a regular sequence with a band crossing. The properties of the dipole sequences are interpreted in terms of ''shears bands'' wit hin the tilted-axis cranking model.
