The angular distribution for the scattering of neutrons by protons was obtained at 14.1 Mev by observing the recoil protons with the use of a counter telescope consisting of a polyethylene target, two proportional counters, and a CsI scintillator. The dath obtained at scattering angles of 16⁵, errors of about 1%. The ratio of the cross sections at 180 and 90 deg in the center-of- mass system was found to be 1.080 plus or minus 0.016 from a least square fit to the form A + B cos² theta . Therefore, it raay be concluded that anisotropy of the angular distribution is confirmed quite clearly. The absolute values of differential cross sections at various angles were normalized using the total cross section 689 plus or minus 5 mb measured by transmission. The values are in good agreement with the results predicted from the nuclear potentials with one-pion-exchange-tail. (auth)
