Study of theMg24(He3,p)Al26Reaction

The nuclear structure of ${}_{}{}^{26}{}_{}{}^{}\mathrm{Al}$ has been studied by means of the ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}({}_{}{}^3{}_{}{}^{}\mathrm{He},p)$ reaction at an incident energy of 18 MeV. 65 levels below 7 MeV in excitation were observed with an energy resolution of 18 keV. Systematics of the angular-distribution shapes allow several assignments of the angular-momentum transfer, resulting in some new spin assignments. Distorted-wave calculations have been performed for those states previously thought to be well described in terms of pure two-particle Nilsson configurations relative to a ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ core.
