Abstract

The existence of highest-lying [2 0 2]3/2 orbit among the six Nilsson particle orbits in prolately deformed nuclie was identified along with the rotational band on this orbit. The band members were investigated in 25Al at excitation energies of 6-7.5 MeV in a high resolution 25Mg(3He,t) charge exchange reaction. The comparison of excitation energies with the analogous M1 transitions in 25Mg depicted that the bandhead and the excited members are clearly assigned. The results showed that the bandhead state of the orbit was observed at E x = 6.117 Mev in 25Al by the charge-exchange reaction.
