Elastic and inelastic scattering of 240 MeV 6Li particles from 24Mg and 28Si were measured with the MDM spectrometer. Optical potential parameters for 6Li+24Mg and 6Li+28Si 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 28Si and 24Mg were obtained. E0 strength corresponding to 106-24+34% of the EWSR was identified in 24Mg and 80-20+35% was found for 28Si between Ex=8.0 to 40.0 MeV.
