摘要：
High-spin states in 199Pb and 200Pb have been investigated by in-beam gamma-ray spectroscopy using several different reactions. In addition to an extension of the spherical level scheme, eight (possibly ten) regular sequences of dipole transitions are found. They are built on oblate proton 2p2h states that are coupled to neutron i13/2 excitations. The experimental results are compared to tilted-axis cranking calculations. A new way of generating regular bands is suggested, that combines collective rotation with a continuous and simultaneous reorientation of neutron and proton spins into the direction of the total angular momentum.
