The expressions for the asymmetry, which are due to linear or circularly polarized photon beam; asymmetries, which are caused by vector or tensor polarized deuteron target; coefficients of spin correlation were calculated. An approach to radiative semi - leptonic decay of tau- lepton description was developed. The amplitudes for the decay of polarized tau leptons, which can be produced in electron - positron annihilation in modern colliders were calculated. Vector and axial - vector form factors are calculated. The Stokes parameters of the final photon are calculated for a detailed study of the process.
