Abstract

Analyzing powers for p^→→pp(¹S₀)π^- were measured at beam energies 353, 404, and 440 MeV by extracting the quasifree process from p^→d→pppπ^-. Partial wave amplitude analysis yields a significant contribution from the isospin 1, s-wave channel. This contribution is relatively much larger than that expected from theoretical models which have been successful in describing the isospin 1, s-wave channel behavior of pp→ppπ⁰ cross sections at threshold.
