F065800100004 AUTHOR (J.J.Lawrie,A.A.Cowley,D.M.Whittal,S.J.Mills, F065800100005 W.R.McMurray) F065800100006 INSTITUTE (3SAFNAC) F065800100007 REFERENCE (J,ZP/A,325,175,1986) F065800100008 FACILITY (VDG) 6 MV F065800100009 DETECTOR (SI) The 100 mu silicon detectors mounted on F065800100010 rotatable arms, with an angular accuracy of 0.1 degr. F065800100011 Circular detector collimators subtended a solid angle F065800100012 of 0.5 msr with an angular acceptance of 0.8 degr. F065800100013 SAMPLE The target consisted of 250 mu-g/cm2 natural silicon F065800100014 evaporated onto a backing consisting of a 40 mu-g/cm2 F065800100015 gold layer on a KAPTON film. F065800100016 MONITOR Forward angle elastic scattering from a thin gold F065800100017 target, measured on both sides of the beam, was used toF065800100018 determine the angular offset of the angle F065800100019 determinations. F065800100020 Rutherford scattering from the thin gold layer F065800100021 sandwiched between the silicon target material and the F065800100022 KAPTON backing, was used to monitor the total incident F065800100023 flux. F065800100024 ERR-ANALYS (ERR-S)Statistical error F065800100025 (ERR-SYS)Systematic error in the measured cross sectionF065800100026 values, which is mainly due to uncertainties in the F065800100027 silicon and gold target thicknesses. F065800100028 (DATA-ERR)The experimental error bars represent F065800100029 statistical errors only.
