O090500100024 DETECTOR (TRD) The solid state nuclear track detector (SSNTD). O090500100025 The delayed alpha-particles were detected. O090500100026 (SCIN) The solenoid and telescope (STAR) method. O090500100027 Beam particles and Na-20 nuclei were stopped in Ta foilO090500100028 behind the target: positrons from Na-20 were separated O090500100029 from Ne-19 positrons and detected in a stack of plasticO090500100030 scintillator. O090500100031 COMMENT - By authors. All measurements were carried out in O090500100032 inverse kinematics - an intense Ne-19 beam bombarded O090500100033 a target.

O090500200012 ERR-ANALYS (ERR-S) The error that arises in these measurements O090500200013 has two components: the first is associated with O090500200014 statistics and normalization, and is by far dominated O090500200015 by statistics - typically 40%, the normalization errorO090500200016 being typically 10%. O090500200017 (ERR-5) The second component is systematic and has two O090500200018 origins: O090500200019 1. In all three measurements, the upper resonant O090500200020 state, 3.07 MeV, was covered only partly, due to its 35O090500200021 KeV width, O090500200022 2. The 1.5 microbarn value was included as a negative O090500200023 contribution to the systematic error in the star-H/2 O090500200024 measurement.
