Elastic Scattering of 190-Mev Deuterons by Protons

The elastic differential scattering cross section of 190-Mev deuterons by protons has been measured from 15^∘{} to 170^∘{} in the center-of-mass system. The cross sections were obtained by subtracting the carbon counts from those received with a polyethylene target. Part I presents a description of the experiments. Results are shown in Table IV and Fig. 3. Part II compares these results with those expected from theory by making use of a method developed by Chew. A summary of this comparison is given in Table VII. Some nucleon-nucleon interactions involving tensor forces give reasonable agreement between theoretical and experimental results, whereas interactions involving purely central forces appear inadequate.
