Abstract

We have studied the reactions Mg24(,p)27Al and Al27(3He,t)27Si to obtain independent evidence regarding the structure of states selectively populated in the Mg26(p,-)27Si reaction. High-spin two-particle one-hole configurations have been inferred from (p,-) studies for states in Si27 at excitation energies of 7.0 and 9.5 MeV. The (,p) data provide evidence for two possible (13/2)+ states in the isobaric analog nucleus Al27 at excitation energies of 6.98 and 9.59 MeV, while the (3He,t) data provide evidence for a possible (13/2)+ state at 9.49 MeV in Si27. These results support the inferences drawn from the (p,-) studies and the use of the A(p,-)A+1 reaction as a spectroscopic tool in identifying high-spin final states having a simple two-particle, one-hole configuration with respect to the target nucleus, which may not be easily reached or identified by other means.
