Abstract
High - spin states in Rb-81 were populated in the Mn-55(Si-30,2p2n) re action at 130 MeV. Prompt gamma gamma gamma - charged particle coincid ences were observed using the GASP spectrometer in conjunction with th e Delta E-E silicon ball (ISIS). A superdeformed band consisting of se ven gamma - ray transitions has been identified. The dynamic moment of inertia for the band is constant with a value of approximately 26.7 h (2)/MeV throughout the whole observed rotational frequency. This band is interpreted to have a pi 5(1)v5(2) intrinsic intruder configuration with a quadruple deformation beta(2) of 0.51.
