P-odd effects at electroexcitation of nucleon resonances

P-odd effects have been calculated for the process of electroexcitation of barion resonances on nucleons: e-N→e-N*. The structure of matrix elements of the operator of the hadron neutral weak current between N and N* states is studied. Obtained are the expressions for the structural functions, describing the cross section of the e-N→e-N* process, in terms of the weak inelastic form factors of a nucleon. The asymmetry of longitudinally-polarized electron scattering by a nonpolarized nucleon target has been calculated. As would be expected, the asymmetry is defined by P-invariance breaking both in hadron and in lepton neutral weak currents
