A parameterization of on-mass-shell relativistic fermion scattering amplitudes by a set of 4 covariant amplitudes is proposed, which in the non-relativistic limit turn to coefficients of the matrix amplitude decomposition over the unity and Pauli matrices, and in the ultra-relativistic limit – to sy...
