A0713001 16 MONITOR (82-PB-208(4-BE-9,EL)82-PB-208,,DA,,RTH) A0713001 17 To provide an absolute normalization for the scatteringA0713001 18 yield, two monitor detectors were used. These were A0713001 19 silicon surface barrier detectors, positioned at ~15 A0713001 20 degree to the beam. A0713001 21 DETECTOR (TELES,SIBAR,SIBAR) A0713001 22 An array of telescopes using position sensitive siliconA0713001 23 detectors enabled reaction products to be identified A0713001 24 and their energy and scattering angle to be recorded A0713001 25 (to improve the angular resolution, masks with ten A0713001 26 slots were placed in front of the telescopes). A0713001 27 ADD-RES (POT) Optical model parameters were deduced at some A0713001 28 density model of 9-Be. A0713001 29 Fusion cross section was calculated too.
