Measurement of Absolute Fission Yields in the Fast Neutron–Induced Fission of Actinides:²³⁸U,²³⁷Np,²³⁸Pu,²⁴⁰Pu,²⁴³Am, and²⁴⁴Cm by Track-Etch-cum-Gamma Spectrometry

Mass distribution in the bremsstrahlung-induced fission of 232Th, 238U and 240Pu

“…Based on the above data, it can be seen that in the neutron- and bremsstrahlunginduced fission of actinides, the yields of fission products are higher around mass numbers 133-135, 138-140 and 143-145 and their complementary products depending on the mass of the fissioning systems [21,22]. However, the yield of fission products around mass numbers 133-135 is more pronounced compared to mass numbers 143-145, in both neutron- [28][29][30][31][32][33] and bremsstrahlung-induced [61][62][63][64][65][66][67][68][69][70][71][72][73][74] fission of uranium isotopes and heavier actinides.…”

“…The yields of fission products relevant to mass and charge distribution studies in the neutron-induced fission of actinides from Ac to Fm and the spontaneous fission of heavier actinides are available in different compilations [10][11][12][13]. However, most of the fission yield data available in the literature are for the thermal neutron- [10][11][12][13] or reactor neutron-induced [14][15][16][17][18][19][20][21][22] fission of actinides. For mono-energetic neutron-induced fission, most of the data available are for actinides induced by either 3 or 14 MeV neutrons [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Product yields for the photo-fission of 209Bi with 2.5 GeV bremsstrahlung

“…From the observed c-ray activities (A obs ), the cumulative yield (Y) of fission products was calculated by using the standard decay equation [4,5] Y…”

“…3. We did not consider charge distribution corrections [4,5,49,50,53] The absolute cumulative yields of various fission products and their complementary products in the 65 MeV bremsstrahlung-induced fission of 209 Bi from our earlier work [50] are also plotted as a function of their mass number for comparison in order to compare those obtained at 2.5 GeV, as shown in Fig. 4.…”

“…Sufficient data for neutron and bremsstrahlung-induced fission of actinides in the low energy region are available in the literature [1][2][3][4][5][6][7][8][9][10]. From all these data, it is clear that the mass-yield distribution in the low energy neutron and bremsstrahlung-induced fission of actinides are asymmetric with fine structure due to shell closure proximity and odd-even effects.…”
