The Fossati-Pinelli study of the scission point configuration of /sup 252/Cf based on the calculations of trajectories of long-range ..cap alpha.. particles emitted in fission provides previously unavailable experimental evidence supporting the basic assumption of the statistical theory of nuclear fission. However, their stated conclusion and that of a similar analysis by Krishnarajulu and Mehta need modification. It is found that the broad and fluctuating distributions of initial energies of the ..cap alpha.. particle and the fission fragments obtained by these two groups might not be real even though they are mathematically valid. Nevertheless, together with other information available to us, the unreal part may be eliminated and both works then yield results that are wholly consistent with the statistical theory of fission. The validity of the dynamical theories will be discussed.
