Polarization in the (p,. pi. ) reaction

Conference · · AIP Conf. Proc.; (United States)
OSTI ID:5740944
Recent experimental results indicate a dominance of fundamental NN..-->..NN..pi.. processes in near-threshold nuclear pion production. Such two-nucleon processes are revealed in part by distinct polarization effects characterizing both weak (ground state) and strong, highly selective, maximal J coupling transitions for the (p,..pi../sup -/) reaction. For (p,..pi../sup +/), where several NN processes can contribute coherently, analyzing power data suggest a means of distinguishing the contributions from different fundamental NN..-->..NN..pi.. isospin channels.
