Abstract

The elastic scattering cross section of deuterons on hydrogen (dσ/dΩ)c.m., is measured in the proton's c.m. angular range θp = 115°–170° at bombarding energies of 433, 362 and 291 MeV. The results at 291 MeV agree with earlier measurements at 140 MeV proton bombarding energy. The differential cross section at 180° obtained by extrapolation of the data to θp = π decreases rapidly with increasing energy as predicted by a nucleon-exchange mechanism. Furtherevidence that nucleon-exchange dominates is found in the behavior of (dσ/dΩ)c.m. at large angles. In this energy range, as well as at higher bombarding energies (equivalent to 632 MeV deuterons), (dσ/dΩ)c.m. is universally dependent on the momentum-transfer variable of the nucleon-exchange mechanism [Δ = (94cos Θp + 12tf)12] (tf is the four-momentum tra for elastic scattering). The purpose of the experiment has been to determine the D-state probability PD through the medium of the neutron-exchange mechanism. Preliminary calculations not reported here suggest that the differential cross section between 1 and 2 fm−1 is quite sensitive to PD.
