Title: Angular distribution of the longitudinal p(vector sign)p(vector sign) spin correlation parameter A{sub zz} at 197.4 MeV

Abstract

A polarized proton beam with a large longitudinal polarization component of 0.545{+-}0.005 (96% of the total polarization) was prepared in a storage ring (IUCF-Cooler). This was achieved by means of spin precession solenoids in two of the six straight sections of the ring. A polarized hydrogen storage cell target internal to the ring was used to measure the longitudinal spin correlation coefficient A{sub zz} in pp elastic scattering over the laboratory angular range 5.5 degree sign -43.5 degree sign ({theta}{sub c.m.}=11.5 degree sign -90 degree sign ) with statistical errors of typically 0.025. The absolute normalization was determined to an accuracy of 2.0% by use of the identity A{sub yy}-A{sub xx}-A{sub zz}{identical_to}1 at {theta}{sub c.m.}=90 degree sign . The identity also allows a reduction of the scale factor uncertainty of the previously published analyzing powers and spin correlation coefficients. The results are compared to recent pp partial wave analyses and NN potential models. (c) 2000 The American Physical Society.
