Observation of Fermi and Gamow-Teller strength in the 800 MeV(p,n) reaction

Journal Article:

Abstract

Angular distributions have been measured for the (p,n) reaction on targets of /sup 6/Li, /sup 12/C, /sup 13/C, and /sup 15/N at 800 MeV with an energy resolution of 2.7 MeV allowing observation of discrete nuclear levels. As is the case at lower energies, this reaction is very selective, emphasizing Gamow-Teller (GT) and Fermi transitions. Absolute cross sections of pure GT transitions are reproduced by impulse approximation calculations. The ratio vertical strokeJsub(sigmatau)vertical stroke/sup 2//vertical strokeJsub(tau)vertical stroke/sup 2/ was extracted from /sup 13/C and /sup 15/N measurements at 800 MeV and from a /sup 13/C measurement at 318 MeV.
