Abstract
The nucleus 202Bi was populated via the 196Pt(11B,5n)202Bi reaction at a beam energy of 75 MeV. Three regular sequences of magnetic dipole transitions have been found. A comparison is made with the known Delta I=1 rotational bands seen in the neighbouring Pb nuclei. An interpretation in terms of collective oblate configurations involving high-K proton and alignable neutron orbitals is suggested.Keywords
