Abstract: (APS)

Forward-angle cross sections for 1+ states have been measured in 24,26Mg, Si28, and S32 by 201 MeV proton inelastic scattering. Comparisons are made with (γ,γ’), (e,e’), and (p,n) results. The measured strength is compared with microscopic distorted-wave Born approximation calculations using large-scale shell-model wave functions. Ratios of experimental to theoretical 1+ strengths are given. Almost no quenching is observed.
