“…It can easily be checked that for the case of a linear polarization of the laser field (η = 0), the phase φ 0 = 0 and the results of S.M. Li et al [1] are straightforward to obtain whereas for the circular polarization (η = π/2), we find the results previously found by Y. Attaourti et al [2]. Eq.…”

We study the effects of the relativistic electronic dressing in laser-assisted electron-hydrogen atom elastic collisions. We begin by considering the case when no radiation is present. This is necessary in order to check the consistency of our calculations and we then carry out the calculations using the relativistic Dirac-Volkov states. It turns out that a simple formal analogy links the analytical expressions of the differential cross section without laser and the differential cross section in presence of a laser field PACS number(s): 34.80. Qb, 12.20.Ds

We study the electron scattering from the freely movable spin-5 proton in the presence of a linearly polarized laser field in the first Born approximation. The dressed state of the electron is described by a time-dependent wave function derived from a perturbation treatment (in a laser field). With the aid of numerical results we explore the dependencies of the differential cross section (DCS) on the electron-impact energy. Due to the mobility of the target, the DCS of this process is modified compared to the Mott scattering, especially in large scattering angles. PACS number(s): 34.80.Qb, 34.80.Dp Physics related to the radiative processes experienced by free electrons inside a strong electrom agnetic field w ere studied since the advent o f laser sources in the early 1960s [1,2]. An overview on this field can be found in the textbooks by Faisal [3], M ittlem an [4], Fedorov [5], and som e other recent papers [6-8]. M ost o f these studies are carried out in the regim e o f nonrelativistic collisions and for low-or m oderate-field intensities. There are also som e studies that have been carried out to investigate theoretically the relativistic potential. In the presence o f ultrastrong lasers, a relativistic treatm ent becom es im perative (even for slow electrons). In the treatm ents o f Refs. [9-11], effects related to the electron spin have been neglected, and the electron has been considered as a K lein-G ordon particle. Based on the theory of Refs. [12,13], Szym anow ski e ta l. [14] and Szym anow ski and M aquet [15] investigated the spin effect in the relativistic potential scattering in the presence o f a circularly polarized field. However, as they stated, the resulting expression for the circularly polarized field turned out to be m ore tractable than for the general case o f elliptical or linear polarizations, and then Li et al. studied the case o f a linearly polarized field [16], A ttaourti et al. studied the cases o f circularly and elliptically polarized fields [17], and M anaut et al. investigated the case o f polarized electrons [18]. The present B rief Report addresses the problem o f an electron scattering off the freely m ovable target in the presence o f a m onochrom atic linearly polarized hom ogeneous laser field. The aim o f this B rief R eport is to add som e physical insight and to show the m odification o f a differential cross section (DCS) due to the m ovable target and com pare it to the case o f M ott scattering. We investigate, to be specific, the recoil effect in relativistic scattering o f an electron from a freely m ovable proton. A DCS is derived by the trace procedure with the aid o f FEYNCALC [19] and M athem atica, and a sim plified form is given for specific cases. U nless specifically stated, atom ic units h = m = e = 1 are used throughout, and the m etric tensor is g^ = diag(l,-1,-1,-1).In the regim e o f laser field intensity as considered in this B rief Report, the field can be treated as classically, w hich does not allow pair creation [20], its four-potential that sa...

Comment on “Mott scattering in strong laser fields”

Abstract: The first differential cross section for Mott scattering of a Dirac-Volkov electron is reviewed. The expression (26) derived by Szymanowski et al. [Physical Review A 56, 3846,(1997)] is corrected. In particular, we disagree with the expression of
