    "abstract": "If scattering amplitudes are ordinary complex numbers (not quaternions) there\nis a universal algebraic relationship between the six coherent cross sections\nof any three scatterers (taken singly and pairwise). A violation of this\nrelationship would indicate either that scattering amplitudes are quaternions,\nor that the superposition principle fails. Some possible experimental tests\ninvolve neutron interferometry, K_S-meson regeneration, and low energy\nproton-proton scattering.",
