The (t, ±) reaction at 17 MeV triton energy has been used to study proton hole states in targets of Pd106,108,110. The results indicate that for the residual nuclei, Rh105,107,109, the ground states have a spin of 72+, in contrast to the lighter Rh nuclei, and are not of single-particle character. Coupled-channels analysis indicates a possible particle-vibration character for these ground states. A strong neutron-proton interaction may be evident from the level systematics of Rh nuclei as the ground state spins change between N=58 and N=60 (Rh103 and Rh105).
