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 C 12 , Al 27 , Ni 58 , Ag, Sn, Au 197 and Bi 209 have been measured by a scintillation counter telescope. Several prominent peaks were observed on C 12 , Al 27 and Ni 58 while very few on Ag, Sn, Au 197 and Bi 209 . 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 ( q r ) 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.
