Cross-section and analyzing power data from (p, p) scattering to the 6- states at 11.58 and 14.35 MeV in 28Si, taken with 80, 100, 134, and 180 MeV protons, have been analyzed using a distorted wave approximation with microscopically defined wave functions. The results of our analyses of those data, taken in conjunction with the analysis of an M6 electron scattering form factor, suggest that in the specification of the two states, ∼ 25 % and ∼ 36 - 40 % respectively of the strengths of isoscalar and isovector 0 dfrac(5, 2)-1 - 0 ffrac(7, 2) excitations from the ground state as described by a Skyrme-Hartree-Fock model. The energy variation of data also suggests that the non-central components of the effective interactions at 80 and 100 MeV may need to be enhanced.
