Giant resonances in O-16
Abstract
Giant resonances in O-16 have been studied with inelastic scattering of 240 MeV alpha particles at small angles, Isoscalar E0, E1, and E2 strength corresponding to 48 +/- 10%, 32 +/- 7%, and 53 +/- 10%, of the respective energy-weighted sum rule was identified between E-x = 11 - 40 MeV with centroids of 21.13 +/- 0.49, 21.67 +/- 0.61, and 19.76 +/- 0.22 MeV and root-mean-square widths of 8.76 +/- 1.82, 7.10 +/- 0.52, and 5.11 +/- 0.17 MeV, respectively. Elastic scattering and inelastic scattering to states at 6.13, 6.92, and 11.52 MeV were measured from theta (c.m.) = 2.5 degrees to 11.5 degrees.
