ENTRY C2035 20130711 C134C203500000001 SUBENT C2035001 20130711 C134C203500100001 BIB 11 34 C203500100002 TITLE Studies of Plutonium, Neptunium, and Uranium Produced C203500100003 in the 244Pu + 136Xe Reaction C203500100004 AUTHOR (W.M.Jae) C203500100005 REFERENCE (J,KNS,13,(3),139,1981) C203500100006 INSTITUTE (3KORKOR) Hanyang Univ., Seoul C203500100007 FACILITY (LINAC,1USABRK) C203500100008 SAMPLE (94-PU-244,ENR=0.986) The target 215 micrograms of C203500100009 244Pu electrosprayed onto a 12.5 micrometers Be foil. C203500100010 The diameter was 6.3 mm yielding the average target C203500100011 thickness of 672 micrograms/cm2. C203500100012 DETECTOR (PROPC,SOLST) Beta proportional counter and alpha C203500100013 proportional counter were used to measure beta and C203500100014 alpha activities, respectively. Alpha pulse analysis C203500100015 of Pu sample was carried out using gold-plated C203500100016 surface barrier detector. C203500100017 PART-DET (B-,A) C203500100018 METHOD (CHSEP,BSPEC,ASPEC) Reaction products were collected C203500100019 on the aluminum catcher foil and dissolved with 10M C203500100020 sodium hydroxide then removed rare earths and C203500100021 transition elements with lanthanide fluoride C203500100022 precipitation method. The residual alpha and beta C203500100023 activities were measured with proportional counters. C203500100024 ANALYSIS (DECAY) From the observed decay curves isotopes were C203500100025 identified. The cross section for each isotope was C203500100026 calculated as: sigma = m/(I*N*(1-exp(-lambda tb))*(1- C203500100027 exp(-lambda tc))*c*gc*gb), where m is counting rate C203500100028 after the cooling, I is intensity of Xe ion per min, C203500100029 N is initial counting rate, tb is bombardment time of C203500100030 244Pu target, tc is chemical separation and cooling C203500100031 time, lambda is decay const for each isotope, c is C203500100032 counting efficiency, gc is chemical yield for each C203500100033 element, gb is ratio of total activity to given C203500100034 activity.
