Comparing spin observables in the reaction $^{12} C(\vec p,\vec p')^{12} C$ at 100–500 MeV with various distorted-wave impulse approximations

Abstract

Spin observables in the process \((\vec p,\vec p')\) are analyzed at intermediate energies in the range 100–500 MeV. Experimental and theoretical data are compared for the reaction \(^{12} C(\vec p,\vec p')^{12} C\) involving excitation of states 1+, T = 0 (12.71 MeV) and 1+, T = 1 (15.11 MeV). Two varieties of DWIA-type calculations are mainly used, allowing the role of isospin effects to be distinguished.
