Abstract |
For the purpose of the present investigation we have considered three different kinds of radiation fields filling a specific spacetime region: a photon test field in a flat spacetime background, an exact solution of the Einstein field equations for a strong plane gravitational wave (with single polarization state for simplicity), and an exact solution of the Einstein-Maxwell equations representing the curved spacetime associated with a plane electromagnetic wave. We have studied the scattering of massive test particles propagating in the different fields and have compared the distinctive features of the scattering processes, notably the changes in the particle's linear momentum before and after the interaction with the radiation fields, as well as the corresponding classical cross sections. |
