Mattis has derived six relations among the partial-wave amplitudes for the reaction ..pi..N..-->..pN. From these relations we deduce that the six independent helicity amplitudes for the t-channel isospin-zero reaction may be simply expressed in terms of one unknown function. This leads to definite predictions for the rho-meson density matrix and the absence of nucleon polarization effects, which can be tested directly, without recourse to partial-wave analysis.
