Neutron-proton elastic scattering spin-spin correlation parameter measurements between 500 and 800 MeV. I.CSLandCLL<

Abstract

Final results are presented for the spin-spin correlation parameters CsL and CLL for np elastic scattering with a polarized neutron beam incident on a polarized proton target. The beam kinetic energies are 484, 634, and 788 MeV, and the c.m. angular range is 80"-180". These data will contribute significantly to the determination of the isospin-0 amplitudes in the energy range from 500 to 800 MeV. PACS numberk): 13.75.Q 13.88.+e, 14.20.Pt, 21.30.+ y

“…The apparatus and experimental method used in the present measurements is essentially the same as was described previously [45,46]. Briefiy, the polarized-neutron beam was obtained from the LAMPF polarized-proton beam striking a liquid deuterium target from which the neutrons were collimated at zero degrees [39,40]. All three components of the proton-beam polarization were measured [49]; the neutron-beam polarization was then obtained when each component was multiplied by the appropriate spin-transfer coefficient [19] for the 2H(p, n, ) reaction.…”
