Search for a state in 3He via the p+D→p+d* reaction

Abstract

Excitation functions for the 2H(p,pp)n reaction have been measured at pairs of proton angles chosen so that the p-n system with zero relative energy was at 30 and 90° in the c.m. system. The differential cross sections dσ/dΩ1dΩ2 corresponding to the production of a p-n system with relative p-n energy below 100 keV are presented. The excitation functions cover the incident proton energy range of 7 to 14.5 MeV in 0.5-MeV steps. The energy dependence of the primary interaction has been extracted by using final-stage modifications of the Watson type. No evidence was found for structure in either the excitation function for the differential cross section or in the excitation function for the primary interaction factor.
