Symmetric and asymmetric size (mass) ratios observed in biological particles in nature and child atoms of nuclear fission are explained by using a stochastic momentum conservation law and weakest stability principle, proposed by Naitoh (J. of Physics, 2012). The three-dimensional momentum conservation law considers vector quantity (i.e. velocity), while conventional theories started from Bohr have been based on energy conservation law.
Furthermore, we have shown that the size and mass ratios of those particles are predicted more accurately by using multi-dimensional Taylor expansion in the previous report (Kobayashi and Naitoh, JASSE, 2019).
In this report, we clarify the relationship between the mass distribution of child atoms generated in nuclear fission and the energy level of neutron provided for the nuclear fission. We classified the terms in the stochastic momentum conservation law obtained by using the multi-dimensional Taylor expansion. As a result, it can be explained that mass distribution of atoms generated in the nuclear fission of uranium 235 depends on the energy of neutron collided to the uranium nucleus because neutron having higher input (impact) energy produce stronger flow in the deep region inside the particle, which leads to a symmetric size ratio of the child particle pair.
