摘要
The nonlinear process of electron-positron pair production in the field of a strong electromagnetic wave in a plasma on the basis of the Dirac model is considered. The formulas for angular distribution and total number of electron-positron pairs are obtained. The latter, in the center-of-mass frame of the produced particles, also describe the process of pair production in vacuum by a uniform periodic electric field. The obtained approximate nonlinear solution of the Dirac equation is applicable in the field when the energy of interaction with the Dirac vacuum is comparable to the electron rest mass.
