A021600100013 (EXTB) Typical currents varied between 100 nA for A021600100014 singly charged and 5 nano-Ampere for doubly charged A021600100015 ions. A021600100016 SAMPLE (5-B-10,ENR=0.97) 97% enriched in 11-B, 50 ug/cm2 A021600100017 thick, deposited on a 15 ug/cm2 carbon backing. A021600100018 DETECTOR (SIBAR) Three surface-barrier silicon detectors were A021600100019 used to measure the emitted protons angular A021600100020 distributions, of thickness varying between 1000 and A021600100021 1500 um. Their angular position was such that a A021600100022 nine points angular distribution, from 20 to 140 degr.
