| Abstract: | From the analysis of 817 kinematically resonstructed beta decay events of polarized Λ hyperons for the coefficient αν of the neutrino correlation with respect to the Λ spin, αν = 0.89 ± 0.08, for the coefficient αT of the T-odd correlation σΛ(pe × pν), αT = ?0.14 ± 0.13. The proton recoil spectrum yields …g1/f1… = 0.64 ± 0.06. |
