AbstractAbstract
[en] We report updated analysis results on an np elastic experiment at LAMPF and a pp experiment at the ZGS. We have measured two np spin asymmetry parameters, C/sub LL/ and C/sub SL/, at beam energies 500, 650, and 800 MeV. The cm scattering angles of neutrons measured ranged from 800 through 1800. We observed very large C/sub LL/ at backward angles for the first time. The pp experiment at the ZGS was a measurement of the difference between the pp total cross sections for parallel and antiparallel longitudinal spin states at beam momenta 2.75, 2.92, 3.25, 3.75, and 4.00 GeV/c. These results reveal possible new structures in this momentum range. Masses for these structures are about 2700 and 2900 MeV
