C185900100009 DETECTOR (SCIN) Two 2.54 cm x 2.54 cm scintillators with C185900100010 thickness of 0.635cm were used to define beam. A C185900100011 91/2-inch diameter liquid scintillator counter was C185900100012 placed coaxial with the beam defined by the first two C185900100013 counters and at variable distance. It was connected C185900100014 in anticoincidence with the coincidence output of the C185900100015 first two counters so as to count directly the number C185900100016 of particles removed from the beam. Thin scatterers C185900100017 (sample of 90-95 percent beam transmission) were C185900100018 placed directly after the second crystal counter. C185900100019 METHOD (TRN) Measured using transmission method. C185900100020 ANALYSIS Correction for Coulomb scattering was made from C185900100021 measured data at several small angles larger than C185900100022 zero.Total cross section was obtained by extrapolation C185900100023 of measured data to zero angle.
