Measurement ofCLLandCSLinnpelastic scattering at 484 and 634 MeV

The spin-spin correlation parameters $C_{\mathrm{LL}}$=(L,L;0,0)=$A_{\mathrm{LL}}$ and $C_{\mathrm{SL}}$=(S,L;0,0)=$A_{\mathrm{SL}}$ for np elastic scattering were measured for incident polarized-neutron–beam kinetic energies of 484 and 634 MeV over the center-of-mass angles from ≃80° to 180°. The data are important for determining the I=0 nucleon-nucleon amplitudes. These results are compared with phase-shift calculations.
