C142100100011 INC-SPECT Unpolarized proton beam. C142100100012 SAMPLE Natural graphite targets of 100 and 300 mg/cm2 C142100100013 DETECTOR (MAGSP,MWPC,SCIN) MRS spectrograph. Multi wire C142100100014 proportional chamber followed by scintillation C142100100015 detector. C142100100016 METHOD (EDE,BCINT,TOF) Protons were separated from heavier C142100100017 reaction products by their time of flight from target C142100100018 to focal plane. Data were recorded on magnetic tape C142100100019 in event mode. The beam current was integrated using C142100100020 1H(p,p)1H scattering in a thin polyethylene foil C142100100021 upstream from the carbon target, with the two C142100100022 outgoing protons observed in coincidence. C142100100023 MONITOR (1-H-1(P,EL)1-H-1,,SIG) An absolute calibration of C142100100024 the measured cross section was achieved by replacing C142100100025 the graphite target by a polyethylene foil, thus C142100100026 relating the 11C(p,p)11C cross section to the known C142100100027 1H(p,p)1H cross section. This was done for two C142100100028 different spectrograph angles; the two calibrations C142100100029 agreed. C142100100030 CORRECTION A correction of up to 8% was necessary for the C142100100031 thicker target, to account for the loss by multiple C142100100032 scattering in the target. In addition, the original C142100100033 cross sections required an overall normalization of C142100100034 1.04 by the authors (latest data). C142100100035 STATUS (APRVD) Approved by H.O.
