Abstract

The

{}^{25}{Mg}

(α,t

)^{26}

Al reaction has been studied at

E_{α}

=50 MeV in the region of excitation energy from 5 to 10 MeV with an energy resolution of 20 keV. The fragmentation of the strengths for the stretched

6^{-}

states is found to be consistent with the calculation for an oblately deformed nucleus, in contrast to the prolate shape of the ground-state band.
