The predicted neutrino flux due to B-8 O054800100018 decay is directly proportional to S17(0). If the O054800100019 average value of S17(0) quoted in the paper is O054800100020 introduced into the standard solar model, replacing theO054800100021 presently adopted value of S17(0), the uncertainty in O054800100022 S17(0) will become insignificant compared to other O054800100023 sources of error in the evaluation of neutrino flux O054800100024 from B-8 decay. O054800100025 SAMPLE The 7-Be target was prepared at the ISOLDE by direct O054800100026 implantation of 7-Be at 60 KeV in a copper disk of 12 O054800100027 mm diameter and 1.5 mm thickness. The target is O054800100028 mounted on an arm that is periodically rotated by a O054800100029 microstepping motor out of the beam and in front of a O054800100030 silicon surface barrier detector, registering the O054800100031 delayed alpha-particle following the decay of 8-B. O054800100032 PART-DET (A) From decay of Be-8 (the dauther of B-8) O054800100033 DETECTOR (SIBAR) In the present experiment a 150-mm2, 25 - O054800100034 micrometers silicon surface barrier detector was used, O054800100035 which provided a sufficiently thick depletion layer to O054800100036 stop the alpha-particles from the reaction but O054800100037 minimized the interaction with gamma rays from O054800100038 the 7-Be activity.
