A formula is given for the doubly differential cross section of electron-positron bremsstrahlung which is exact in lowest-order perturbation theory. Angular distributions and energy spectra of the emitted photon are computed in the center-of-mass system and in the laboratory system. The results are compared with available approximations and with the cross sections of electron-electron and electron-proton bremsstrahlung.
