Measurement of Spin-Correlation Parameters all and Asl in P-P Elastic-Scattering from 500 Mev to 800 Mev
MetadataShow full item record
The spin-correlation observable A(LL) for p-p elastic scattering has been measured at energies 589, 640, 692, 743, and 793 MeV, over a c.m. angular range between 20-degrees and 100-degrees. The spin observable A(SL) was also measured in this angular range at energies 640 and 793 MeV. At 488 MeV both the spin observables were measured, but only near the c.m. angle of 90-degrees. The data are compared with the predictions of several phase-shift analyses and previous measurements. The energy dependence of A(LL) for the c.m. angle of 90-degrees is also presented and shows no anomalous behavior. These data provide better angular coverage over five of the energies, with comparable or better statistical precision, than previous measurements of A(LL).
