The data were used to determine O079600100015 number of Li-7 nuclei in used targets. O079600100016 DECAY-DATA (4-BE-7,53.29D,DG,478.,0.1052) O079600100017 SAMPLE Circular targets of Li-F of 2 mm diameter, evaporated O079600100018 on Al and Pt foils. A liquid nitrogen cold cryofinger O079600100019 is placed close to the target area to protect the O079600100020 target surface from contamination. The vacuum in the O079600100021 chamber was 8.E-7 Torr. O079600100022 METHOD (EXTB) A deutron beam (D2+) was raster scanned over a O079600100023 rectangle of 7 mm X 6 mm. The purpose of the scan is O079600100024 to obtain a beam of uniform areal density. O079600100025 (BCINT) O079600100026 (ACTIV) The time sequence of the complete cycle is: O079600100027 1. 1.5 s beam-on-target; O079600100028 2. 100 ms rotation; O079600100029 3. 1.5 s of target in the counting position; O079600100030 4. 100 ms rotation. O079600100031 PART-DET (A) Delayed alphas following the beta-decay of Li-8. O079600100032 DETECTOR (SIBAR) A 40 micron surface barrier detector. O079600100033 The detector was surrounded by a shroud to prevent O079600100034 scattered beam panicles from reaching the detector. O079600100035 FACILITY (VDG,3ISLWZI) 3 MV accelrator. O079600100036 ERR-ANALYS (ERR-T) Total uncertainty of final result is determinedO079600100037 by uncertainties: O079600100038 (ERR-1) Of monitor cross section, O079600100039 (ERR-2) Absolute efficiency of gamma counting, O079600100040 (ERR-3) Systematic error in gamma counting, O079600100041 (ERR-4) Statistic of gamma counting. There is, in O079600100042 addition, a 1% systematic error in the gamma counting O079600100043 due to uncertainty in the background subtraction O079600100044 procedure.
