We measured d[sigma]/dt(90[deg]cm) for [short up arrow]+p[short up arrow]-->p+p from 1.75 to 5.5 GeV/c, using the Argonne zero-gradient synchrotron 70% polarized proton beam and a 70% polarized proton target. We found that the spin-spin correlation parameter.Ann, equals 60% at low energy, then drops sharply to about 10% near 3.5 GeV/c, and remains constant up to 5.5 GeV/c.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/22614/1/0000164.pd
