A045000100003 AUTHOR (S.S.Rattan, R.J.Singh) A045000100004 COMMENT Abstract: the alpha induced fission of 209-Bi has beenA045000100005 carried out at alpha energy of 49.1 MeV and 44.9 MeV A045000100006 using gamma ray spectrometry. The cross sections for A045000100007 The production of ten fission products at alpha energyA045000100008 of 49.1 MeV and four fission products at alpha energy A045000100009 of 44.9 MeV have been determined. The mass A045000100010 distribution has been found to be broad with peak nearA045000100011 mass 103. The cross section for the production ofA045000100012 22-Na, 24-Na and 28-Mg in the alpha induced reaction A045000100013 of 27-Al has been determined at 49.6 MeV and 45.4 MeV. A045000100014 INSTITUTE (3INDTRM) Radiochemistry Division A045000100015 REFERENCE (J,RCA,38,69,1985) A045000100016 SAMPLE The targets of super pure 209-Bi were prepared by A045000100017 vacuum evaporation on 25.4 mum super pure aluminium A045000100018 foil. The targets of 2 mg/cm**2 of bismuth were used A045000100019 for irradiation. In order to avoid the cross A045000100020 contamination of fission products due to large activityA045000100021 of direct reaction products, the 209-Bi target was A045000100022 Covered with a 0.76 mumeter super pure aluminium foil. A045000100023 This will allow the fission products to pass and will A045000100024 prevent the reaction products. The whole assembly was A045000100025 put in a target holder and irradiated for a suitable A045000100026 length of time with a 50 MeV alpha particle beam of 2 -A045000100027 3 muA. The Incident alpha energy on the first bismuth A045000100028 target was 49.1 MeV where as on the second bismuth A045000100029 target it was 44.9 MeV. A045000100030 The bismuth targets and aluminium catchers were A045000100031 separated from each other carefully to avoid cross A045000100032 contamination. The aluminium catchers were mounted A045000100033 separately on perspex plates in suitable geometry.
