S>The electron-proton bremsstrahlung cross section is calculated in first Born approximation, neglecting radiative corrections to the electron. As an extension of an earlier calculation, the proton Compton effect contribution is analyzed in its most general form. It will involve twelve form factors of three invariants: f/sub j/( nu /sub 1/, nu /sub 2/, nu /sub 3/,), (j = 1,...,12) . The cross section is stated explicitly in terms of these twelve functions and the two form factors of one invariant describing the proton vertex. The contributions to the f/sub j/ from the single nucleon intermediate state, the one-meson, onenucleon intermediate state, and the neutron pion exchange, are calculated. These three contributions are expected to be the major effects when the energies involved are in the range of present experimental interest. To order (l/M)/sup 2/ only three combinations of these twelve f/sub j/ will contribute to the cross section. When only the first two contributions are considered, only two of these three combinations are independent. Some numerical values for a bremsstrahlung coincidence experiment are presented. (auth)
