C005700100009 INC-SPECT Mean scattering energy varied between 1299.8 and 200.1 C005700100010 MeV according to target thickness. C005700100011 SAMPLE Several self-supporting targets ranging in thickness C005700100012 between 3.7 and 150 mg/cm3. The targets were of both C005700100013 natural composition and enriched in 12C or 13C. C005700100014 DETECTOR (MAGSP,MWPC,SCIN) Magnetic spectrograph, helical wire C005700100015 chamber in focal plane for position information, C005700100016 followed by 2 plastic scintillators for particle C005700100017 identification. C005700100018 Energy resolution of scattered protons between 100 and C005700100019 500 keV FWHM depending on target thickness and C005700100020 scattering angle. C005700100021 Scattering angle known to better than 0.05 degrees. C005700100022 The angular acceptance was 0.55 degrees for angles C005700100023 of 6-64 degrees, and 0.97 for angles of 68-110 C005700100024 degrees. C005700100025 Beam monitored using Faraday cup.
