摘要：
Neutrino-antineutrino (nu(nu) over bar) pair production is one of the main processes responsible for the energy loss of stars. Apart from the collision of two (gamma gamma -> nu(nu) over bar) or three (gamma gamma gamma - nu(nu) over bar) real photons, pair creation from a photon and photon collisions in the presence of nuclear Coulomb fields or external magnetic fields have been considered previously. Here, we study pair production of a neutrino and antineutrino from a low-energy photon in the presence of a combined homogeneous magnetic field and the Coulomb field of a nucleus with charge number Z.
