O138200100014 SAMPLE A small diameter implanted Be-7 target was used. O138200100015 The target consists of copper, Be-7 and Li-7. After O138200100016 Implantation was 1.17E+16 Be-7 atoms and 10E+15 Li- O138200100017 atoms in a cylindrical volume of copper, 2-mm diameter O138200100018 and 2500-angstroem deep, containing a total of 6.7E+16O138200100019 Cu-atoms the B-8 backscattering loss to be 0.2%, smallO138200100020 enough to be ignored. O138200100021 The target was calibrated for Be-7 content by O138200100022 monitoring the gamma-rays following the Be-7-Li-7-beta O138200100023 decay. O138200100024 METHOD (EXTB) O138200100025 (BCINT) O138200100026 (GSPEC) The gamma measurements were carried out in O138200100027 standard counting arrangements, which however required O138200100028 the gamma-activity of the sample to be below a limit O138200100029 much smaller than the actual activity of used target. O138200100030 It was possible to produced a secondary target about O138200100031 300 times weaker than the primary target, identical O138200100032 with it in all aspects but the gamma activity.

In attempting to compare this results withO138200100043 other recent measurements was note that while this workO138200100044 emphasizes a selected energy point, all other O138200100045 measurements are spread over wide ranges with O138200100046 relatively large individual errors. Those errors in O138200100047 turn are partially statistical and partially systematicO138200100048 and may be common to the whole range.
