The absolute cross section for the $sup 12$C(p,pn)$sup 11$C reaction has been measured in the M2 diffracted proton beam of the Fermi National Accelerator Laboratory at an energy of 300 GeV. Proton intensities were measured with a scintillation counter telescope, and the 20.4-min $sup 11$C activity induced in 3.2-mm thick plastic scintillator targets was determined both by internal scintillation ($beta$) counting and by annihilation radiation counting with a NaI well crystal. A correction for the formation of $sup 11$C by secondary particles was determined by measuring the activity in individual targets in a stack. The corrected value for the $sup 12$C(p,pn)$sup 11$C cross section at 300 GeV is 24.6+-1.6 mb. (AIP)
