O126800100016 SAMPLE A He-4 gas cell with a 8-mm diameter nickel window of O126800100017 0.5 to 1-mum thickness. The gas cell is insulated fromO126800100018 the beam line and the entire chamber, including a O126800100019 Cu-catcher of 50-mm diameter that is in electric O126800100020 contact with the gas cell, serves as a Faraday cup. O126800100021 The He-4 purity of 99.9% was ensured by replacing it O126800100022 periodically every four hours. O126800100023 COMMENT -By authors. The number of beam particles obtained O126800100024 through either the beam current integration or the O126800100025 Rutherford scattering from the nickel foil is the O126800100026 major source of error in the determination of the crossO126800100027 section. O126800100028 Reaction (13-AL-27(P,G)14-SI-28) has been used for beamO126800100029 energy calibration.
