O138400100012 SAMPLE The neptunium layers were prepared by multiple thermal O138400100013 decomposition of neptunium nitrate on 10 mumeters thickO138400100014 aluminium backings. The thickness of the 237-Np layer O138400100015 on each target was about 100 mug/cm2. O138400100016 FACILITY (CYCLO,2SF JYV) K-130 cyclotron. O138400100017 METHOD (STTA) Two sets of eight targets each separated by 10 O138400100018 mumeters thick aluminium foils were irradiated in two O138400100019 irradiations. O138400100020 (EXTB) 40 MeV He+ and 60 MeV He++ ion beams the beam O138400100021 current in both irradiation was about 3 micro-amperes. O138400100022 (ACTIV) During 12 (40 MeV) and 4 (60 MeV) hours.
