And it is found that both sets lead to invariant amplitudes which are not kinematical singularity and zero free. where the K,(p)-standard covariants carry spin-tensorial indices and are polynomial in the four-vectors p = (pl ,...,pn ) [9]. The invariant amplitudes Ai( which are functions of the ind
