NUCLEAR REACTIONS 235U(n, F)236U*,239Pu(n, F)240Pu*, E=thermal MeV; calculated mass distribution of fission fragments, fission product yields, and compared with experimental results and with data in JENDL/FPY-2011 library. 235U(n, F)236U*,239Pu(n, F)240Pu*, E<50 MeV; calculated average total kinetic energy (TKE) of fission fragments, quadrupole moment (Q20) of fission fragments just after scission, dependence of average quadrupole moment (Q20) and average octupole (Q30) of fission fragments, distance between the center of mass of the nascent fragments just after scission using method based on the four-dimensional Langevin equations. Comparison with experimental data. Relevance to decrease of average total kinetic energy of fission fragments as the excitation energy of the compound nuclei increases, as indicated by experimental data of neutron-induced fission reactions.
