Pion production at the lepton scattering by the 6Li nuclei

The general structure of the differential cross section for/→/e- + Li e- + π+ + 6He process with the detection of two particles in the final state (for one-photon mechanism) is obtained. The scattering of nonpolarized and longitudinally polarized electrons by a target with vector and tensor polarization is considered. The polarization phenomena in the e- + 6Li → e- + π+ + 6He are defined by a set of 41 real structure functions. The P-odd polarization phenomena in the e- + 6Li → e- + π+ +6He reaction are also considered which are conditioned by P-odd nuclear forces. Polarization phenomena near threshold of this reaction are studied in detail when P-even amplitude is defined by two form factors, and P-odd amplitude is defined by one. The polarization phenomena in the ν + 6Li → ν + π+ + 6He reaction conditioned by weak neutral currents are also studied in general form
