Fifty years after its prediction, the highest-lying [2 0 2]3/2 orbit among the six Nilsson single-particle orbits originating from the sd shell in prolately deformed nuclei and the rotational band on this orbit were identified. The band members were observed in 25Al at excitation energies of 6-7.5MeV in a high-resolution 25Mg(3He, t) charge-exchange reaction at 0° having a strong selectivity for Gamow-Teller transitions. In comparison with the analogous M1 transitions in 25Mg, the J π=3/2+ band-head state and the excited 5/2+ and 7/2+ members were clearly assigned.
