摘要：

The cross sections for the processes gamma nu --> gamma gamma nu, gamma gamma --> gamma nu<(nu)over bar>, and nu<(nu)over bar> --> gamma gamma gamma are calculated with the aid of an effective Lagrangian derived from the standard model. These cross sections are shown to be much larger than the elastic cross section sigma(gamma nu --> gamma nu) for photon energies omega > 1 keV. Possible astrophysical implications are discussed.
