Abstract It's shown that lepton conservation can be checked oniy in single beta - decay experiments. From beta -decay experiments results arp presented which take into account experimental errors without making theoretical assumptions. It is shown that the negative result found in ordinary time reversal experiments allows no conclusion to be established about time reversal invariance as long as maximum breakdown of parity or conservation of lepton charge has not been established. The beta - interaction is mainly A-V, with contributions from S and T smaller than 10%. Parity violation and polarization of neutrinos is oniy a few percent of the maximum possible value obtained for complete violation of lepton charge conservation. Invariance with respect to time reversal holds with an error of about 15%. The experiments on beta -decay prove lepton conservation and a two state theory with an uncertainty of about 15%. (C.J.G.)
