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