Abstract

Cross sections for the primary pion beam monitor reactions ${}^{12}C (π^{\pm}, π N) {}^{11}C$ (20.4 min) have been measured between 30 and 100 MeV by activation techniques. These cross sections are consistently lower, but within the uncertainties of our previously determined values. The experimental uncertainties of these new measurements are considerably smaller.

NUCLEAR REACTIONS ${}^{12}C (π^{\pm}, π N) {}^{11}C$ measured cross sections by activation, $T_{π} = 30 - 100$ MeV. Plastic scintillator targets; pion flux determined with scintillator telescope.
