Abstract
We investigate the effect of negative-energy states on proton-proton b remsstrahlung using a manifestly covariant amplitude based on a T-matr ix constructed in a spectator model. We show that there is a large can cellation among the zeroth-order, single- and double-scattering diagra ms involving negative-energy nucleonic currents. We thus conclude that it is essential to include all these diagrams when studying effects o f negative-energy states.
