In order to improve existing {ital I}=0 phase shift solutions, the spin correlation parameter {ital A}{sub {ital NN}} and the analyzing powers {ital A}{sub 0{ital N}} and {ital A}{sub {ital N}0} have been measured in {ital n}-{ital p} elastic scattering over an angular range of 50{degree}--150{degree} (c.m.) at three neutron energies (220, 325, and 425 MeV) to an absolute accuracy of {plus minus}0.03. The data have a profound effect on various phase parameters, particularly the {sup 1}P{sub 1}, {sup 3}D{sub 2}, and {epsilon}{sub 1} phase parameters which in some cases change by almost a degree. With the exception of the highest energy, the data support the predictions of the latest version of the Bonn potential. Also, the analyzing power data ({ital A}{sub 0{ital N}} and {ital A}{sub {ital N}0}) measured at 477 MeV in a different experiment over a limited angular range (60{degree}--80{degree} (c.m.)) are reported here.
