The ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^3{}_{}{}^{}\mathrm{He},{}_{}{}^3{}_{}{}^{}\mathrm{He}n){}_{}{}^{11}{}_{}{}^{}\mathrm{C}$ cross section at 910 MeV was measured by using a Ge(Li) gamma spectrometer to determine the disintegration rate and measuring the incident flux by means of a scintillator telescope. Cross sections for the production of ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$ in C and Al and for the production of ${}_{}{}^{24}{}_{}{}^{}\mathrm{Na}$ in Al are then determined using the measured cross section as a monitor.
