A tritium target was bombarded with 5-msec pulses of 6.1-Mev deuterons produced by the Los Alamos variable energy cyclotron. A collimated beam of 22.5- Mev neutrons from the H/sup 3/(d,n)He/sup 4/ reaction was directed into a 3.2- liter liquid-hydrogen bubble chamber. The resulting proton recoil tracks were photographed with 90 deg stereophotography. Film scanning, data reduction, and uncertainties in the measurements are described. The measurements Cover neutron scattering angles from 60 deg to 180 deg in the c.m. system. The measured relative differential cross section in the c.m. system can be written d sigma /d OMEGA = A/sub 0/ + A/sub 2/ cos/sup 2/ theta , where A/sub 2//A/sub 0/ = 0.113 plus or minus 0.03.
