Giant resonances in ²⁴Mg

The giant resonance region in ²⁴Mg was studied with inelastic scattering of 240 MeV α particles at small angles including 0°. The giant resonance peak was found to extend up to E_X=41 MeV. Isoscalar E0, E1, and E2 strength corresponding to 72±10%, 81_-14⁺²⁶%, and 72±10% of the respective energy weighted sum rules was identified in the peak with centroids of 21.0±0.6, 18.8±1.7, and 16.9±0.6 MeV and rms widths of 7.3±1.2, 6.7±1.0, and 3.4±0.5 MeV, respectively. Elastic scattering was measured from θ_c.m.=3° to 33° and density dependent folding model parameters obtained. Inelastic scattering to states at 1.369, 4.122, 4.238, 6.010, 6.432, 7.349, 7.555, 7.616, and 8.358 MeV was measured and B(EL) values obtained.
