摘要
The graviton bremsstrahlung cross section for a spinless particle is obtained by including linear as well as nonlinear gravitational interactions, and the nonemission of nonphysical gravitons is established by direct calculations. The problem of infrared divergence in graviton bremsstrahlung is then resolved, and it is shown that for this purpose it is necessary to include the contributions of both the vertex and the self-energy diagrams in the radiationless scattering. © 1969 The American Physical Society.
