Giant resonances in (24)Mg and (28)Si from 240 MeV (6)Li scattering
Abstract
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(-24)(+34)% of the EWSR was identified in (24)Mg and 80(-20)(+35)% was found for (28)Si between E(x)=8.0 to 40.0 MeV.
