Abstract: High spin states in 108Ag have been studied via in-beam γ spectroscopy techniques using the 104Ru(7Li, 3n) reaction. The previously known level scheme has been extended, and a new band structure has been established. The configurations have been tentatively assigned to all observed rotational bands. The signature splitting behavior of the p g9/2 ⊗ νg7/2 band has been discussed and interpreted as a change in shape from near-oblate to prolate. A systematic study of the nearly degenerate negative-parity bands in the A ~ 110 mass region has been performed and it is found that the yrast band in 108Ag and its side band show different behaviors with those expected from a pair of chiral bands.
