ABS>Neutrons from the Project Gnome nuclear test were resolved in energy by time-of-flight and used to study symmetry of fission in U/sup 235/ in the resonance region. Symmetry was deduced by measurement of the fission product ratio decrease observed in the probability of symmetric fission as compared to the probability in thermal fission of U/sup 235/ was 50%. The maximum increase observed was 22%. Four levels showed an increase in symmetry. Thirteen levels showed a decrease in symmetry. With the exception of one level at 15.4 ev, assignments of levels by symmetry are in agreement, in the region covered, with previous work. (auth)
