Abstract

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.
