Webcurium shows that all energy dependences of fission cross sections in the neutron energy region of 1-20 MeV have similar structural particular features: maxima in the energy intervals of 1-3 MeV and 8-9 MeV and minima in the energy ... the fission cross sections of a given element may be approximated by straight lines. However the results of ... WebJan 1, 1977 · The distribution of mass in spontaneous fission of 248 Cm and 250 Cf has been investigated radiochemically and with γ-ray spectrometry. Both distributions are asymmetric with peak-to-valley ratios of > 1000 for 248 Cm and > 300 for 250 Cf. The average light and heavy masses (A L, A H) are respectively 104.6, 139.9 and 105.2, …
