摘要：

Three cascades of dipole transitions have been identified in 199,200Pb with rather regular energy spacings of about 50 keV. Together with several cross-over transitions they form three rotational bands in these normally spherical nuclei. Arguments are given that the dipole transitions are of M1 multipolarity as opposed to E1 so that these cascades can be interpreted as strongly coupled bands built on high-K oblate states involving proton h9/2 or i13/2 orbitals.
