The scattering of a positron by a muon in the presence of a linearly polarized laser field is investigated in the first Born approximation. The theoretical results reveals: 1) at large scattering angle, an amount of multiphoton processes take place in the course of scattering. The photon emission processes predominant the photon absorption ones. 2) Some nonlinear phenomena about oscillations, dark angular windows, and asymmetry can be observed in angular distributions. We analyze the reason…

Relativistic above-threshold ionization (ATI) and high-harmonic generation in the long pulse regime are investigated via the Klein-Gordon equation employing the strong-field approximation. The energy

Recursive algorithm for arrays of generalized Bessel functions: Numerical access to Dirac-Volkov solutions.

It is shown that the generalized Bessel function can be evaluated, in a numerically stable way, by utilizing a recurrence relation and a normalization condition only, without having to compute any initial value.

Quantum Electrodynamics

THE subject of quantum electrodynamics is extremely difficult, even for the case of a single electron. The usual method of solving the corresponding wave equation leads to divergent integrals. To
