Electromagnetic Decay Strengths in the Isobars 89Nb, 89Mo and 89Tc

Research output: Contribution to journalArticle


Lifetimes of high spin states in the three A = 89 isobars Nb-89, (89)MO and (TC)-T-89 have been measured via the Recoil Distance Doppler Shift technique and the fusion evaporation reactions Ni-58(Cl-35, xnypz alpha) at 120 MeV beam energy. Reduced transition probabilities for about 50 gamma transitions were extracted. The experimental branching ratios in Mo-89 and reduced transition probabilities in all three isobars are compared with the predictions of the spherical shell model based on the restricted pi(p(1/2)), pi(g(9/2)), nu(p(1/2)), nu(g(9/2)) configuration space with two different types of residual interaction.
