D037100100013 SAMPLE The radionuclidic purity of the 237Np target was higherD037100100014 than 99%. There were impurities of 238Pu and 239Pu D037100100015 present in the target material, which contributed to D037100100016 the alpha-activity by 0.000185% and 0.000116%, D037100100017 respectively. Thin and thick targets were prepared. TheD037100100018 thin targets were prepared by the evaporation of D037100100019 0.1 mg/cm2 of neptunium on 6 or 50 mu-m thick aluminiumD037100100020 foils. The neptunium coated foils were stacked in a D037100100021 pile and separated with 6 mu-m thick aluminium foils. D037100100022 One thick neptunium target was made by piling three D037100100023 50 mu-m thick aluminium foils, on which about 2 mg/cm2 D037100100024 of neptunium was first painted as neptunium nitrate D037100100025 celluloze and then transformed to neptunium oxide by D037100100026 thermal decomposition. In the thick target the D037100100027 neptunium coated foils were also separated with 6mu-m D037100100028 aluminium foils. D037100100029 A total of ten irradiations were carried out: nine D037100100030 with thin neptunium targets and one with a thick D037100100031 neptunium target.
