An upper limit is found on the difference between the cross sections for the interactions of thermal neutrons with opposite helicities with 233U: Ρ = (σ+ σΓ+ σ') < 1.5Χ ΙΟ"6 (at a 90% confidence level). This result contradicts the value Ρ = 10"4-10-5 estimated under the assumption that the 0.17-eV level is a ^-wave level.
