The positive-parity yrast states in the {sup 91}Y and {sup 95}Nb nuclei have been studied by {gamma}-ray spectroscopy following heavy-ion-induced fusion-evaporation reactions. The lowest-lying transitions in these structures have been assigned via the p2n channel of the reactions of {sup 12}C (38 MeV) and {sup 16}O (48 MeV) beams with a {sup 82}Se target, studied at the Bucharest Tandem accelerator. More detailed level schemes have been determined subsequently in a study performed with the GASP array of the inverse reactions produced by a {sup 82}Se (470 MeV) beam from the Legnaro Tandem-LINAC accelerator with oxygen and possibly carbon contaminants of a {sup 192}Os target. The observed level schemes are compared with local systematics and shell-model calculations.
