The excitation function for the reaction O106400100014 U-238(d,2n)Np-238 determined by measuring the Pu-238 O106400100015 decay product, but the activities were very low. O106400100016 SAMPLE Uranium foils, thickness 50-mg/cm**2, were intercalatedO106400100017 with aluminium degraders and copper foils used as beam O106400100018 monitors. Enrichments-93% U-235 and 99.9% U-238. O106400100019 DETECTOR (GELI) For monitor activity O106400100020 FACILITY (ISOCY,2UK HAR) The Harwell's Variable Cyclotron . OO106400100021 METHOD (STTA) O106400100022 (ACTIV) The time of irradiation was 8-hours with a beamO106400100023 current of 2-muA for U-235 and 6.6-hours with 7-muA forO106400100024 U-238. O106400100025 (CHSEP) O106400100026 (GSPEC) After the irradiation, the samples were left O106400100027 for cooling for three months to allow the decay of mostO106400100028 of the fission products and of the Np-234, which emits O106400100029 the same X-rays as Np-235.
