Phys. Rev. E 66, 016502 (2002) [6 pages]Electron-positron pair production in the field of superstrong oppositely directed laser beamsReceived 10 December 2001; revised 26 February 2002; published 29 July 2002 The multiphoton electron-positron pair production through nonlinear channels by superintense opposed laser pulses of the same frequencies in vacuum is considered. On the basis of the Dirac model the resonance approximation for vacuum induced transitions is developed. The analytic formulas for energetic and angular distributions and total number of created particles in the limit of a short interaction time are obtained. © 2002 The American Physical Society URL:
