Abstract
The level structure of odd-proton was studied using the F,4n) reaction. Gamma-gamma coincidence, angular distributions and γ-γ-time measurements were used to establish the energies, spins, parities, and lifetimes for the states in the decay scheme of . Both prolate and oblate structures have been established. The prolate bands are built on the π (α=±(1/2) and the π (α=(1/2) particle states. An oblate, strongly coupled band built on a 90±10 ns isomeric state is reported for the first time. A second oblate structure built on the proton-hole state was established to much higher spin than before. The backbend present in the π band has been interpreted as the alignment of a pair of protons.
