Analyzing powers for the proton excitation of high-spin states in 28Si: A new look at the effective interaction

Abstract

Analyzing powers have been measured for the 5 −, T = 0, 6 −, T = 0 and 6 −, T = 1 high-spin states in 28Si using the inelastic scattering of polarized protons at 135 MeV. These data contain new information on the spin-independent central and the tensor components of the effective nucleon-nucleon interaction at high momentum transfer. The new measurements are in reasonable agreement with distorted-wave impulse approximation calculations.
