The value of the Ρ-οάά asymmetry coefficient of the fragment emission in the fission of 235U through the capture of thermal polarized neutrons has been measured by the integral method. The asymmetry coefficient is equal to (0.84 + 0.06)X10 ~4. The restriction on the P-odd asymmetry in the reactions 10B(n,a)7Li:|a| <0.5X 10 "5 and 6Li(n,f)4He:|a| < 1.0X 10~5 are obtained (90% confidence level). A right-left asymmetry has been found in the 6Li(«,/ )4He reaction; the asymmetry coefficient is equal to (0.95 ± 0.4) X 10 ~4.
