M058600100012 METHOD (MAGFR) 900 MeV/C magnetic spectrometer. M058600100013 DETECTOR (MWDC,SCIN) Counters were constructed from NE110 M058600100014 plastic scintillator sheets of thicknesses 1.6, 2.3, M058600100015 3.1, 12.5, and 12.5 mm coupled to RCA 8575 M058600100016 phototubes.

M058600100020 ERR-ANALYS (ERR-S) Statistical errors. M058600100021 (ERR-SYS) The overall systematic uncertainty is 7%. M058600100022 COMMENT Inclusive photoproton cross section Cu(gamma,p)x have M058600100023 been measured for a photon energy of 300 MeV at M058600100024 proton angles 45, 90, and 135 degree, and for 150 MeV M058600100025 at 45 degree. The data were compared with an M058600100026 intranuclear-cascade calculation and with Ni(pi,p) M058600100027 data. The angular distribution was analyzed to obtain M058600100028 an estimate of the number of nucleons involved in the M058600100029 interaction.
