Spin correlationAnnand analyzing powerAinppppat 643 MeV

Abstract
The spin correlation parameter Ann and the analyzing power A have been measured at 643 MeV from 35 to 90° c.m., with statistical uncertainties of ±0.01 to ±0.02 and normalization uncertainty of ±2%. The data are in fair agreement with phase shift predictions and with the trend of most previous data near this energy.
