Description
Summary:We have investigated the properties of low-tyiag states iu 96Ru within the framework of the neutron-proton interacting boson model （IBM-2）, with special attention paid to the characteristics of the mixed symmetry states. By considering the relative energy of d proton boson to be different from that of neutron boson, the level energies and M1, E2 transition strengths have been calculated. The IBM-2 calculation is consistent with the experimental data of 96Ru both quantitatively and qualitatively. Particularly, the strong M1 transition between the 42^＋ and 41^＋ states has been reproduced nicely. The calculated results show that the M1 transition strength of B（M1,42^＋ → 41^＋） in 96Ru carl be described successfully by the IBM-2.
