n−pScattering at 300 Mev

An investigation of the protons scattered by 300-Mev neutrons has been conducted with a Wilson cloud chamber filled with hydrogen at a gas pressure of ten atmospheres. The data obtained cover the range of angles 10°-180° for the neutrons in the center-of-mass system. A striking deviation from symmetry appears in that backward scattering is considerably larger than forward scattering. The energy spectrum is presented for the neutrons that are produced in a $1\frac{3}{4}$-in.-thick LiD target by 340-Mev protons. A few cases of meson production are noted. Also, there is presented experimental evidence for the radiative capture of high-energy neutrons in hydrogen.
