O061500100011 (R,O0193001,S.Baba+,J,NP/A,175,177,1971) Authors used O061500100012 the results to derive the appropriate FWHM values, O061500100013 the centers of the light and heavy peaks and the O061500100014 mass number of the centre of the whole mass O061500100015 distribution.

O061500100017 (A,T0044003,G.L.Bate+,J,PR,133,B1471,1964) O061500100018 FACILITY (CYCLO,3RUMBUC) Y-120 cyclotron O061500100019 SAMPLE The target assembly consisted of several natural O061500100020 uranium targets 1.2 mg/cm2 thick, each being sandwichedO061500100021 between 4.2 mg/cm2 aluminum catcher foils to stop the O061500100022 fission products and to degrade the proton beam energy.O061500100023 The targets were prepared by depositing a solution O061500100024 of uranium acetate on aluminum backings. O061500100025 DETECTOR (GELI) A 15 cm3 Ge-Li detector. O061500100026 METHOD (BCINT) Relative beam monitoring. O061500100027 (EXTB,STTA,EDEG) The energy values in the stack O061500100028 were calculated from tables - See REL-REF. O061500100029 The Initial proton energy was 13.2 MeV. O061500100030 (ACTIV,FPGAM) Direct Gamma-Ray Spectrometry O061500100031 of unseparated fission products. O061500100032 MONITOR (92-U-238(P,F),,SIG) O061500100033 MONIT-REF (P0028001,G.R.Choppin+,J,PR,131,2149,1963) Data were O061500100034 normalized at 11.9 MeV. The cross section of the given O061500100035 reaction is not compiled in the given EXFOR Entry. O061500100036 ASSUMED The product mass distribution was constructed with O061500100037 an assumption that there are two independent modes O061500100038 of fission, symmetric and asymmetric, each of them O061500100039 of a Gaussian form. O061500100040 ANALYSIS (DECAY) The gamma emitters were identified by comparingO061500100041 the energy values, the half-lives and the relative O061500100042 gamma lines intensities.
