MEASUREMENT OF THE ANGULAR-DISTRIBUTION OF NEUTRON-PROTON SCATTERING AT 10 MEV

The relative angular distribution of neutrons scattered from protons w as measured at an incident neutron energy of 10 MeV at the Ohio Univer sity Accelerator Laboratory. An array of 11 detector telescopes at lab oratory angles of 0-60 degrees was used to detect recoil protons from neutron interactions with a CH2 target. Data for seven of these telesc opes were obtained with one set of electronics and are presented here. These data, from 108 to 180 degrees for the center-of-mass scattering angles, have a small slope which agrees better with angular distribut ions predicted by the Arndt phase shifts than with the ENDF/B-VI angul ar distribution.
