    "abstract": "We investigate the effect of negative-energy states on proton-proton\nbremsstrahlung using a manifestly covariant amplitude based on a T-matrix\nconstructed in a spectator model. We show that there is a large cancellation\namong the zeroth-order, single- and double-scattering diagrams involving\nnegative-energy nucleonic currents. We thus conclude that it is essential to\ninclude all these diagrams when studying effects of negative-energy states.",
