High-spin states in odd-odd sup(100,102,104)Rh

High-spin excited levels of sup(100,102,104)Rh have been investigated in the sup(96,98,100)Mo(7Li,3nγ) reactions. Standard in-beam γ-ray measurements involving relative excitation functions, γγt coincidences, angular distributions and linear polarization have been performed. Three level schemes including states up to I=14 are proposed. This study gives the relative position of the 2- and 6+ states of 102Rh, which is also confirmed by an additional decay measurement. The analogy between the three level schemes has been pointed out. Especially, a ΔI=1 negative-parity band based on a 8- level has been established and interpreted in the framework of the rotor-plus-two-quasiparticle (πgsub(9/2)νhsub(11/2)) model. (orig.)
