Abstract

High-spin states in 201Pb and 202Pb have been investigated using in-beam γ-ray spectroscopic techniques. Seven regular sequences of enhanced dipole transitions, with weak E2 crossovers in some cases, have been found, one of which is firmly connected to low-lying levels in 201Pb. These bands are interpreted to be built on high-spin proton-particle neutron-hole excitations. Tilted-axis cranking calculations show that the angular momentum along the bands is predominantly generated by a continuous and simultaneous reorientation of the proton and neutron spins into the direction of the total angular momentum (shears effect).
