Giant resonances in 24Mg and 28Si from 240 MeV 6Li scattering

Elastic and inelastic scattering of 240 MeV 6 Li particles from 24 Mg and 28 Si were measured with the MDM spectrometer. Optical potential parameters for 6 Li + 24 Mg and 6 Li + 28 Si scattering systems were obtained by fitting elastic scattering with two different folding model potentials as well as W-S potentials. E0-E3 giant resonance strength distributions for 28 Si and 24 Mg were obtained. E0 strength corresponding to 106 +34 -24 % of the EWSR was identified in 24 Mg and 80 +35 -20% was found for 28 Si between E x = 8.0 to 40.0 MeV.
