Abstract
High spin states in203, 205Bi, populated in the203, 205Tl (α,4n) reactions, have been studied using gamma-ray and conversion-electron spectroscopy. Several previously unobserved isomeric transitions were identified by electron-electron coincidence measurements in both isotopes and in205Bi a new isomer was found. The observed states can be explained as arising from couplings of the oddh 9/2 proton to neutron states in the neighbouring Pb cores. Reduced transition probabilities are derived and discussed.
