(p→,n) reaction on carbon isotopes atEp=160MeV

Differential cross sections and analyzing powers for the (p\ensuremath{\rightarrow},n) reaction on carbon isotopes have been measured for angles up to ${\ensuremath{\theta}}_{\mathrm{lab}=50}$\ifmmode^\circ\else\textdegree\fi{} using 160 MeV protons. The angular distributions for the stronger transitions are compared with the results of distorted-wave impulse approximation calculations which utilize transition densities from existing shell model calculations. The total observed Gamow-Teller strength is also compared with the shell model predictions. In addition, the shapes of these angular distributions are discussed emphasizing decomposition into longitudinal, transverse, and non-normal-parity-transfer components. Some comparisons of the present (p,n) data with corresponding (p,p') data and with other relevant (p,n) data are also made.
