### Abstract

A polarized proton beam with a large longitudinal polarization component of [Formula Presented] (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 [Formula Presented] in [Formula Presented] elastic scattering over the laboratory angular range [Formula Presented]–[Formula Presented]–[Formula Presented] with statistical errors of typically 0.025. The absolute normalization was determined to an accuracy of 2.0% by use of the identity [Formula Presented] at [Formula Presented] 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 [Formula Presented] partial wave analyses and [Formula Presented] potential models.
