O059200100004 AUTHOR (S.S.Parikh,D.A.Marsden,N.T.Porile,L.Yaffe) O059200100005 INSTITUTE (1CANMCG) O059200100006 REFERENCE (J,CJC,45,1863,1967) O059200100007 SAMPLE The targets were natural uranium foils, ranging in O059200100008 thickness from 0.001-in. to 0.003-in. Target foils O059200100009 were sandwiched between two similar foils to compensateO059200100010 for recoil losses during irradiation. O059200100011 The monitor foil was similarly sandwiched and the two O059200100012 packets aligned with the target downstream from the O059200100013 monitor. O059200100014 FACILITY (SYNCY,1CANMCG) O059200100015 METHOD (CHSEP) O059200100016 (ACTIV) Irradiation time varied from 3 min. to 1 hour. O059200100017 (INTB) O059200100018 (STTA) O059200100019 ADD-RES (Z-DIS) O059200100020 CORRECTION Corrections were made for chemical yield,aliquot factorO059200100021 and overall efficiency of counting system. O059200100022 COMMENT - By Authors - All investigated nuclides have O059200100023 short-lived parents and thus corrections had to be madeO059200100024 for growth from the parent during the irradiation O059200100025 period and before chemical separation. O059200100026 In each case, two uranium targets were irradiated at O059200100027 each energy with appropriately chosen periods of O059200100028 irradiations and periods elapsing between the end of O059200100029 bombardment and separation to optimize these O059200100030 corrections. Both targets were processed identically O059200100031 and the activities measured under identical conditions.O059200100032 ANALYSIS (DECAY) O059200100033 ERR-ANALYS (ERR-T) It is estimated probable error. The error ariseO059200100034 from uncertainties in weighing, pipetting, decay curve O059200100035 analyses, counter efficiency, chemical yield O059200100036 determination and uncertainties in monitor cross O059200100037 sections and statistical error. O059200100038 (ERR-S,,1.) Statistical error O059200100039 No errors have been assigned to conversion coefficient O059200100040 values used. half-life values used agreed well with theO059200100041 best literature values and no errors were assigned to O059200100042 the decay constants.
