Abstract

The spin-correlation parameter $A_{nn}$ for free n-p elastic scattering has been measured for the first time for incident-neutron-beam energy $E_{n}$ =790 MeV and c.m. angles 48°≤ $θ^{*}$ ≤149°. The data are compared with the widely differing predictions of several phase-shift analyses, clearly favoring one of them. They also are compared with recently published quasifree $A_{nn}$ data for the more limited c.m. angular region 98°≲ $θ^{*}$ ≲122°.
