D607700100012 The fission products were collected on 25.4 micro-meterD607700100013 thick aluminum foil by recoil catcher technique. D607700100014 The whole assembly was put in a target holder and D607700100015 irradiated for a suitable length of time with 100 MeV D607700100016 19F particle beam of ~100 nano-ampere. D607700100017 Average incident energy of 19F on the bismuth targets D607700100018 was 99.2 MeV. D607700100019 DETECTOR (HPGE) D607700100020 METHOD (BCINT) D607700100021 (ACTIV,EXTB) Four irradiations were carried out for D607700100022 varying duration of time from around 2 and 12 hours so D607700100023 as to cover both the short and long lived fission D607700100024 products. D607700100025 (GSPEC) The decay of the activity for the fission D607700100026 products was followed from a few minutes to a few days D607700100027 for the short irradiations and from a few hours to D607700100028 10 days for the longer irradiations. D607700100029 The cumulative production cross section was determined D607700100030 for most of the mass chains. In case of shielded nucleiD607700100031 independent production cross section was determined. D607700100032 COMMENT Fission product yield studies in the reaction of D607700100033 99.2 MeV 19F with 209Bi have been carried out using D607700100034 gamma-ray spectrometry. Cross sections for the D607700100035 production of fission products have been determined. D607700100036 Yield distribution of fission products was found to be D607700100037 symmetric and broad with FWHM around 22 mass units and D607700100038 peak near mass 111. The average number of neutrons D607700100039 emitted per fission has been found to be around 6.7. D607700100040 Comparison of the fission products yield distribution D607700100041 of 209Bi using projectiles like 4He, 12C, 16O, and 19F D607700100042 have shown that the mass of symmetric peak increases asD607700100043 the mass of the compound nucleus increases. D607700100044 High fission yield around mass 112 has been attributed D607700100045 to the presence of deformed neutron shells. D607700100046 Total fission cross section and width of the mass D607700100047 distribution have been found to be low in case of 16O D607700100048 induced fission as compared to the 4He, 12C, and 19F D607700100049 induced fission of 209Bi.

The independent yield D607702700005 and cumulative yield of a fission product in a given D607702700006 mass chain was assumed to be in the Gaussian form. D607702700007 In the absence of data on the width of the distributionD607702700008 (Sz) and most probable charge (Zp), the Zp was D607702700009 determined assuming unchanged charge distribution D607702700010 (UCD). Since, neither the data on Sz nor on average D607702700011 number of neutrons emitted per fission (vT) was D607702700012 available for 209Bi(19F,f), hence these were determinedD607702700013 by fitting the experimental yields to the equations in D607702700014 an iterative manner. D607702700015 An average value of vT was assumed and the YA for the D607702700016 fission products was determined. Calculated YA was D607702700017 used to arrive at the new vT value. The input and D607702700018 calculated vT were compared. The input vT value was D607702700019 varied between 5 to 10 to arrive at the appropriate D607702700020 value of vT. This whole process was repeated for D607702700021 various Sz values from 0.8 to 1.1. YA were compared forD607702700022 all these Sz values to arrive at the best fit. D607702700023 The input value of vT = 6.7 for 99.2 MeV gave the best D607702700024 fit for the YA distribution at Sz = 0.90.
