A032200100004 AUTHOR (S.Baba,K.Hata,M.Izumo,R.Motoki,T.Sekine) A032200100005 INSTITUTE (2JPNJAE) A032200100006 FACILITY (VDGT,2JPNJAE).Using the JAERI tandem accelerator A032200100007 one of the targets was bombarded with 18 MeV deuteron A032200100008 and the other with 25 MeV deuterons. A032200100009 REFERENCE (J,ARI,36,564,1985) A032200100010 METHOD (ACTIV,STTA,BCINT,EDEG,CHSEP) A032200100011 SAMPLE Two targets were used, each made from stacked foils A032200100012 containing neptunium layers and aluminum foils to A032200100013 degrade the energy of the deuterons. A032200100014 About 30 days later both neptunium targets and A032200100015 aluminum foils (which contained plutonium recoils) A032200100016 were dissolved in nitric acid. A032200100017 Finally, a neptunium target was bombarded to obtain A032200100018 the cross section s for (d,p) and (d,p+2n) reaction A032200100019 at 21 MeV. A032200100020 COMMENT /By authors/.the yields of Pu-236 and Pu-238 were A032200100021 measured by alpha spectrometry and from the knowledge A032200100022 of the yield of plutonium. A032200100023 ADD-RES The anion exchange method mentioned earlier was used A032200100024 to separate the plutonium from neptunium, aluminum A032200100025 and from fission products, and the purified plutonium A032200100026 was evaporated onto a stainless steel disc when its A032200100027 alpha spectrum was measured with a surface barrier A032200100028 detector.
