C2895001 12 DETECTOR (SIBAR,SILI,TELES) The detection system consisted of C2895001 13 a double-collimator system and a solid-state detector C2895001 14 telescope. The detector telescope consisted of a 1-mm C2895001 15 Si surface-barrier deltaE-detector and a 4-mm Si(Li) C2895001 16 E-detector rotated to 60 degrees to produce an C2895001 17 effective thickness of 8 mm. C2895001 18 SAMPLE The target consisted of a 12 cm diameter gas cell C2895001 19 filled with high-purity helium gas to a pressure of C2895001 20 approximately 1 atmosphere. C2895001 21 METHOD (EXTB,EDE) C2895001 22 ADD-RES (POT) The optical-model parameters were calculated.
