摘要：

Graviton interactions with a charged fermion and a photon axe studied in the context of linearized gravity coupled to QED. It is found that, apart from an overall kinematical factor, each graviton interaction process has essentially the same transition-amplitude structure as the process involving a photon in place of the graviton. While the angular dependence of cross sections in both cases is different due to the overall factor, the polarization effects of the graviton are identical to those of the corresponding photon, except that the graviton Stokes parameters enter instead of the photon Stokes parameters. The consequences of the electromagnetic and gravitational low-energy theorems and some possible extensions of our results axe discussed.
