C244800100009 (R,,J.Terrell,J,PR,127,880,1962) Neutron correction C244800100010 method. C244800100011 INSTITUTE (1USALAS) C244800100012 FACILITY (VDGT,1USALAS) LASL FN tandem Van de Graaff. C244800100013 SAMPLE A 50 microg/cm2 target of 241Am which had been C244800100014 prepared by vacuum evaporation onto a 3 mm diam spot C244800100015 on a 30 microg/cm2 C foil. C244800100016 DETECTOR (TELES) C244800100017 METHOD (EDE,COINC) The direct reaction protons were recorded C244800100018 with a dE-E counter telescope which consisted of a C244800100019 300 microm transmission detector and a 2 mm depletion C244800100020 depth E detector. The telescope was located at 125 C244800100021 with respect to the beam axis. Two 300 mm2 fission C244800100022 fragment detectors, which were collinear in the C244800100023 center of mass system, were located at ~90 degrees to C244800100024 the recoil axis as defined by the counter telescope. C244800100025 Triple coincidence events were measured between the C244800100026 two fission detectors and the outgoing proton. C244800100027 ANALYSIS The energies and masses of the coincident fission C244800100028 fragments were obtained using the "mass defect" C244800100029 calibration procedure. The primary fission C244800100030 calibration standard was 252Cf. C244800100031 CORRECTION Neutron correction based on method of Terrell.
