The C173200100013 telescopes, part of the High Resolution Array, C173200100014 consisted of a 65 mu-m thick, single-sided Si-strip C173200100015 dE detector followed by a 1.5-mm-thick, double-sided C173200100016 Si strip E detector.All Si detectors were 6.4 x 6.4 C173200100017 cm2 in area with their position-sensitive faces C173200100018 divided into 32 strips. C173200100019 METHOD (EDE) C173200100020 INC-SOURCE Primary beam of 10B at E/A = 15.0 MeV impinged on a C173200100021 hydrogen gas cell held at a pressure of 2 atm and C173200100022 kept at liquid-nitrogen temperature.A secondary beam C173200100023 of 10C with energy of E/A = 10.7 MeV was produced C173200100024 through the 10B(p,n)10C reaction and separated from C173200100025 other reaction products using the momentum achromat C173200100026 recoil spectrometer MARS.
