An Experimental Survey of Nuclear Reactions Induced by 57 MeV Protons Part II (p, d) Reactions

Abstract

With 57 MeV incident protons, energy spectra of deuterons from the (p, d) reactions on C¹², Al²⁷, Ni⁵⁸, Ag, Sn, Au¹⁹⁷ and Bi²⁰⁹ have been measured by a scintillation counter telescope. Several prominent peaks were observed on C¹², Al²⁷ and Ni⁵⁸ while very few on Ag, Sn, Au¹⁹⁷ and Bi²⁰⁹. The energy resolution was about 2.5% at half maximum. Angular distributions were obtained for the prominent peaks and were analyzed in terms of j_l(qr)² and of Butler curves. The peaks are considered to correspond to removal of neutron leaving a hole in a single particle state occupied in the target nucleus. In some cases, however, residual interactions may be taken into account. No clear peak was observed in the region of Q value less than about −25 MeV.
