Abstract

Excitation of isovector giant resonances in ${}^{27}{Al}$ was studied by using the ${}^{27}{Al}$ $(^{7}$ Li, ${}^{7}{Be}$ $)^{27}$ Mg reaction at incident energies of 100, 150, and 180 MeV. We observed the analog of the giant dipole resonance at $E_{x}$ =14.3 MeV in ${}^{27}{Mg}$ . From the observed excitation function, we suggest that a peak at $E_{x}$ =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.
