Examination of Final States in Charged Pion Electroproduction from ^3He
Abstract
JLab Experiment 91003 measured cross sections for pion electroproduction from H, ^2H, and ^3He. Data were obtained at Q^2=0.4 GeV^2, for W=1.15 and W=1.60 GeV. For negative pion production from ^3He, only a three proton (p-p-p) final state is possible. For positive pion production (p-n-n), (^2H-n), and (^3H) final states are accessible. An outline of the experiment and missing mass distributions in ^3He showing separation of final states will be presented along with preliminary coherent pion production cross sections.
