The giant-resonance region of /sup 24/Mg, /sup 27/Al, and /sup 28/Si was studied by inelastic scattering of 126-MeV ..cap alpha.. particles. In contrast to results at 96 MeV, considerable clustering of E2 strength was observed for /sup 27/Al at E/sub x/ approx. 20.1 MeV with GAMMA approx. 7.6 MeV exhausting about 35% of the E2 energy weighted sum rule. E2 strength was also located in /sup 24/Mg in two clusters of states at E-bar/sub x/ approx. 18.2, 24.4 MeV; however, contributions from other multipoles cannot be neglected. In /sup 28/Si a multipeaked group was observed at E/sub x/ approx. 19.4 MeV with GAMMA approx. 4 MeV but no L assignment was made. The energy dependence of the cross section for the giant quadrupole resonance was found to be consistent with distorted-wave Born approximation predictions.
