Excited states have been populated in In-108 and In-110 in complementary backed- and thin-target experiments, using the Stony Brook and the 8 pi Ge-detector arrays. The level schemes for both isotopes have been extended and modified, including the first observation of DeltaI = 2 bands in In-110. Lifetimes of states in four DeltaI = 1 bands and one DeltaI = 2 band have been measured using the Doppler-shift attenuation method. Experimental total angular momenta and reduced transition strengths for the DeltaI = 1 bands have been compared with tilted axis cranking predictions for shears bands with configurations involving one proton g(9/2) hole and one or three valence quasineutrons from the h(11/2) and g(7/2)/d(5/2) orbitals. The DeltaI = 2 bands have been compared with principal axis cranking predictions for configurations with two g(9/2) proton holes and a g(7/2) or d(5/2) proton and one- or three-quasineutron configurations involving the h(11/2) and g(7/2)/d(5/2) orbitals. In general, there is good overall agreement for both the angular momenta and reduced transition strengths. The DeltaI = 1 and DeltaI = 2 bands have large J((2))/B (E2) ratios as expected for the shears mechanism. The B (M1) strengths deduced for the DeltaI = 1 bands show a decreasing trend as a function of spin, which is also a feature of the shears mechanism. Configuration assignments have been made for most observed bands based on comparisons with theory and systematics of neighboring nuclei. |
