Excitation of isovector giant resonances in 27Al by heavy ion charge exchange reaction.

Excitation of isovector giant resonances in /sup 27/Al was studied by using the /sup 27/Al(/sup 7/Li, /sup 7/Be)/sup 27/Mg reaction at incident energies of 100, 150, and 180 MeV. We observed the analog of the giant dipole resonance at E-italic/sub x-italic/ = 14.3 MeV in /sup 27/Mg. From the observed excitation function, we suggest that a peak at E-italic/sub x-italic/ = 9.5 MeV is a resonance with a higher multipolarity than one. In the excitation energy region higher than the giant dipole resonance, no resonance was observed.
