  The Coulomb effect hypothesis in cold fission, formerly used to interpret
fluctuations in the curve of maximal total kinetic energy as a function of
fragments mass, in reactions 233U(nth,f), 235U(nth,f) and 239Pu(nth,f), is
confirmed by the preference for more asymmetrical charge splits observed in
cold fragmentations. Several experimental results on reactions 233U(nth,f) and
235U(nth,f) show that, for two isobaric fragmentations with similar Q-values,
the greater is the value of the kinetic energy of the fragments, the greater
will be the probability of more asymmetric charge split.
