Giant Quadrupole Resonance inMg24,26: A Comparison of Inelastic-Scattering andα-Capture Experiments

The distribution of giant quadrupole resonance strength in /sup 24,26/Mg obtained from inelastic ..cap alpha..- and proton-scattering experiments and ..cap alpha..-capture experiments have now been shown to be compatible. The results show that the giant quadrupole resonance strength in /sup 24/Mg and /sup 26/Mg is fragmented into several states or clusters of states and suggest that the giant quadrupole resonance states have very different ..cap alpha../sub 0/-decay strength.
