D037900100012 FACILITY (CYCLO,3INDVEC) D037900100013 METHOD (EXTB,SITA) D037900100014 The numer of incident alpa-particles was normalized D037900100015 through measurement of the integrated charge collected D037900100016 on a Faraday cup fixed at the rear end of the chamber. D037900100017 DETECTOR (SIBAR) Six silicon surface barrier detectors of D037900100018 different thicknesses ranging from 1000 to 2000 mu-m D037900100019 were placed on two movable arms on either side of the D037900100020 beam direction. The detectors on each arm were placed D037900100021 15. degr. apart. Two monitor detectors were placed at D037900100022 30. degr. on either side of the beam direction for D037900100023 relative normalization. D037900100024 ERR-ANALYS (DATA-ERR) The absolute error, due to uncertainties D037900100025 in target thickness and solid angle measurements.
