The coefficients of the P-odd asymmetry in the separation of light and heavy fragments during double and triple fission of U-233 nuclei by polarized neutrons have been measured simultaneously in an experiment in a polarized-neutron beam at the ILL high-flux reactor. The ratio of the coefficients for triple and double fission turns out to be 1.05 + 0.10. This result is evidence that the fission channels for double and triple fission are approximately the same.
