Abstract: | We present calculations of laser-assisted differential cross-sections in the second Born approximation. We explore effects of off-the-energy-shell propagation, and we conclude, contrary to other works, that this effect, although significant when compared to the second Born on-shell approximation, is too small for the second Born approximation to account for experimental results.Received: 20 January 2004, Published online: 9 March 2004PACS: 34.80.Qb Laser-modified scattering - 34.50.Rk Laser-modified scattering and reactionsS.
