Soft photon approximation in a laser field: applications
Peter A. Krachkov, Simon V. Sorokin
We apply the soft photon approximation to QED processes in a strong plane-wave laser field. New compact expressions for the emission factors are presented, which simplify the gener…
Single-quantum annihilation of positrons at low energies
Peter. A. Krachkov, Simon. V. Sorokin
We discuss the single-quantum positron annihilation with a bound electron in the near threshold region. The angular distribution and the total cross section are considered. We obta…
Soft photon approximation in a laser field
P. A. Krachkov
In the present paper, we consider processes involving the emission of soft photons in the presence of a strong laser field. We demonstrate that the matrix element for a process…
Atomic screening and pair photoproduction at low energies
P. A. Krachkov, A. I. Milstein
The effect of screening by atomic electrons on the behavior of electron and positron wave functions in the continuous spectrum at small distances is studied. It is shown that these…
Resonant amplification of a relativistic electron bremsstrahlung on an atom in the undulator field
P. A. Krachkov, A. I. Milstein, N. Yu. Muchnoi
It is shown that the influence of the undulator field on the motion of a relativistic electron leads to a significant increase of the bremsstrahlung cross section on an atom near t…
Photoproduction of pair in a Coulomb field near the threshold
P. A. Krachkov, R. N. Lee, A. I. Milstein
We consider the electron-positron pair production by a photon in Coulomb field near threshold. We obtain the analytical results for the particle energy spectrum and angular distrib…
