説明
Cross sections for (p, $x\mathrm{n}$), (p, $\mathrm{p}x\mathrm{n}$), and (p, $2\mathrm{p}x\mathrm{n}$) reactions of Ti, Fe, Co, Ni, Cu, and Zn isotopes at 12 GeV were determined from spallation yield data measured with a Ge(Li) $\ensuremath{\gamma}$-ray spectrometer. Among the measured cross sections which include associated pion production the (p, n) reactions show a large target dependence. The cross sections for $^{57}\mathrm{Fe}$(p,n)$^{57}\mathrm{Co}$, $^{65}\mathrm{Cu}$(p,n)$^{65}\mathrm{Zn}$, $^{48}\mathrm{Ti}$(p,n)$^{48}\mathrm{V}$, and $^{56}\mathrm{Fe}$(p,n)$^{56}\mathrm{Co}$ are 14.9\ifmmode\pm\else\textpm\fi{}2.4, 2.69\ifmmode\pm\else\textpm\fi{}0.20, 1.64\ifmmode\pm\else\textpm\fi{}0.26, and 0.58\ifmmode\pm\else\textpm\fi{}0.04 mb, respectively.
