Abstract:Comment on "Pion Absorption on the Diproton"In a recent Letter, Piasetzky et al l report a phaseshift analysis of cross-section data for the quasifree absorption (in 3 He) of 62.5-MeV n~ by a ^o proton pair. The analysis produces five discrete possible solutions (for l n -p P ^2), yielding quite different predictions for the polarization P y (6) of the outgoing nucleons. We point out here that analyzing powers A y (9) measured for (ppoN^~) reactions on nuclei may already provide the (quasifree) polarization da… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
