“…The laser-assisted (e,2e) collision [ 25 ] is a sort transition between the photon and electron projectiles. For the normal (e,2e) processes—which dominated the program in 2000—nowadays they only perform a small amount of calculations.…”

Many particle spectroscopy is a subject of continued interest to many experimental and theoretical groups worldwide. It is based on the coincidence spectroscopy of minimum two particles coming from the same elementary process. It is a very powerful tool for studying not just atoms and molecules but also more extended electronic systems such as clusters and surfaces. Due to the large variety of its applications, it is really an interdisciplinary research field. This Topical Issue presents a state-of-the-art description of current research activities in the field of many particle spectroscopy. The contributions to this Issue represent original research results on both experimental and theoretical studies, involving the interaction of various projectiles, like photons, electrons, ions with atoms, molecules, clusters and surfaces.

“…For this purpose, we use our recently developed nonperturbative approach for computing laser-modified Coulomb scattering states [8], which we already have successfully utilized in the theoretical treatment of the laser-assisted (e, 2e) process of atomic hydrogen [9]. Our method makes use of quasi-Sturmian (QS) basis functions [10] taken in parabolic coordinates to solve the system of coupled Lippmann-Schwinger-Floquet equations in the Kramers-Henneberger representation [11]. Because of the adequate asymptotic behavior of the parabolic QS functions, from the obtained solution one can easily extract the scattering amplitude for a given net number of exchanged photons.…”

We present a theoretical analysis of a charged-particle scattering by a Coulomb potential in the presence of laser radiation. The effect of a laser field is studied using our recently developed nonperturbative parabolic quasi-Sturmian approach for solving the system of coupled Lippmann–Schwinger–Floquet equations in the Kramers–Henneberger frame. We calculate the ratio of multiphoton differential cross sections to the Rutherford cross section in the case of a laser-assisted electron-proton scattering process. Our results are compared with predictions of the Bunkin–Fedorov, Kroll–Watson, and Coulomb–Volkov analytical approximations: marked discrepancies are found for different net numbers of exchanged photons and different orientations of the laser-field polarization vector. Our findings clearly demonstrate deficiencies of those well-known approximations for describing laser-modified Rutherford scattering processes.

Synopsis We demonstrate the robustness and efficiency of our recently formulated quasi-Sturmian-Floquet method to treat light-dressed electron states. For this purpose we study the archetypical processes such as laser-modified electron scattering on a Coulomb potential and laser-assisted electron-impact ionization of atomic hydrogen. For both processes we explore various regimes of laser radiation and identify the differences with respect to the corresponding laser-free situations.
