Abstract
Differential cross section and polarization predictions are presented for medium energy (E p ≧ 100 MeV) (p, n) reactions on light closed shell nuclei. The influence on the predicted cross section of various spin or momentum dependent effective interactions is studied. We stress the advantage of comparing the (p, n) experimental results with recent or anticipated (e, e′) experiments leading to the excitation of T = 1, high spin, non-normal parity “particle-hole” states. It is argued that by doing (p, p′) and (p, n) at medium energies with machines possessing high beam current, variable energy and good resolution, one should be able to make significant progress in understanding both the reaction mechanism and the relevant nuclear structure. Specific examples of exotic states that are predicted to be observable at large momentum transfer are a 6 −, T = 1 (1 f 7 2 ) (1 d 5 2 ) − state in 28Si(p, n) 28P ∗ and a 4 −, T = 1 (1 d 5 2 ) (1 p 3 2 ) − state in 16O(p, n) 16F ∗. Form factor minima associated with wave function radial nodes may also be observable.
