Abstract

Lifetimes of high spin states in the threeA=89 isobars89Nb,89Mo and89Tc have been measured via the Recoil Distance Doppler Shift technique and the fusion evaporation reactions58Ni(35Cl,xnypzα) at 120 MeV beam energy. Reduced transition probabilities for about 50γ transitions were extracted. The experimental branching ratios in89Mo and reduced transition probabilities in all three isobars are compared with the predictions of the spherical shell model based on the restrictedπ(p 1/2),π(g 9/2), ν(p1/2),ν(g 9/2) configuration space with two different types of residual interaction.
