The proton hole states of /sup 95/Y and /sup 95,97,99/Nb have been studied by the (t,..cap alpha..) reaction using a polarized beam of 17 MeV tritons on targets of /sup 96/Zr and /sup 96,98,100/Mo. The results yield a number of new levels as well as numerous new spin assignments based on the large analyzing powers characteristic of the (t,..cap alpha..) reaction. Examination of the systematics of the resulting level schemes indicates a tendency towards deformation with increasing neutron number, which is expected given the known deformed region above A = 100. However, /sup 97/Nb is also clearly affected by the N = 56 subshell closure. This subshell closure has a major effect on the level structure of /sup 96/Zr but is completely washed out in /sup 98/Mo.
