Positive pion scattering on 24Mg
Joyce, Donald
Joyce, Donald
Abstract
The reaction ('24)Mg(pi('+), piN) and the angular correlation between ('24)Mg first excited state deexcitation gamma rays and the nuclear recoil direction following pion inelastic scattering were studied at 200 MeV by means of coincidence measurements of outgoing charged particles and nuclear deexcitation gamma rays. The angular distribution of both pions and protons in coincidence with ('23)Na and ('23)Mg first excited state deexcitation gamma rays is consistent with those expected from quasi-free scattering. Comparison of results with final state nucleon charge exchange models suggests that final state nucleon charge exchange plays a minor role in single nucleon knockout reactions. The preliminary measurement of the angular correlation betwen ('24)Mg('2+) deexcitation gamma rays and the nuclear recoil direction is similar to the angular correlation W((theta)) = sin('2)(2(theta)) expected for non spin flip transitions.
