O0604 1 7 AUTHOR (Z.Todorovic,R.Antanasijevic) O0604 1 8 INSTITUTE (3SRBBKB) O0604 1 9 FACILITY (SYNCY,1USAANL) 12.2 GeV O0604 1 10 (SYNCH,2ZZZCER) 14, 18 and 23 GeV O0604 1 11 REFERENCE (J,NC/A,33,546,1976) O0604 1 12 SAMPLE Layers of gold of a thickness of 200-500 Angstrom O0604 1 13 were evaporated in vacuum onto one of the detector O0604 1 14 foils on the inner side. O0604 1 15 The surface of the sample was parallel to the proton O0604 1 16 beam for the irradiation at 12.2 GeV and normal to the O0604 1 17 proton beam for irradiations at the other energies. O0604 1 18 METHOD (FISCT) O0604 1 19 DETECTOR (TRD) Makrofol polycarbonate detectors consisted of O0604 1 20 two sheets of a size of 3*4*0.02 cm forming a sandwich.O0604 1 21 Detector was sensitive to fragments with A>=16. Heavy O0604 1 22 reaction fragments were stopped inside the Makrofol O0604 1 23 sheets and could thus be detected in a 4pi geometry. O0604 1 24 CORRECTION Performed: Loss of events of about 2% due to removal O0604 1 25 of the detector material in the course of chemical O0604 1 26 treatment. O0604 1 27 Negligible: Casual coincidences between two individualO0604 1 28 tracks and an individual track with binary events. O0604 1 29 ERR-ANALYS (ERR-T) Statistics of the fission events and the O0604 1 30 uncertainties in the flux determination and the target O0604 1 31 thickness. O0604 1 32 (ERR-1,,15.) Error in flux determination O0604 1 33 (ERR-2,,10.) Error in target thickness. O0604 1 34 (ERR-S) Statistics of the fission events. O0604 1 35 ADD-RES (RANGE) O0604 1 36 The range of the fragments and the distributions of O0604 1 37 the space angle between two tracks for two- and O0604 1 38 three-prong events.
