  In a recent letter we suggested a natural generalization of the flat-space
spinor-helicity formalism in four dimensions to anti-de Sitter space. In the
present paper we give some technical details that were left implicit
previously. For lower-spin fields we also derive potentials associated with the
previously found plane wave solutions for field strengths. We then employ these
potentials to evaluate some three-point amplitudes. This analysis illustrates a
typical computation of an amplitude without internal lines in our formalism.
