Non-resonance electron scattering in the field of two plane light waves

Abstract

Here, Ei , pi are the energy and momentum of an electron in the centre-of-mass system before scattering. As it was shown in c1, 2, 41 in the frames of (l)-( 2) the resonances may arise only at the onward or backward scattering of a small angle 6 N w/pi < 1 (0 is the angle of scattering). Thus, the nonregion is defined by (in the centre-of-mass Non-resonance electron scattering in the presence of two electromagnetic waves, for q, 4 1, is investigated theoretically. The expression for partial section of electron scattering with radiation and absorption of arbitrary number of external field photons is obtained. This expression is analyzed for different electron energies. The cross-section dependencies of electron angular scattering is presented for different wave polarizations.

Nonresonant scattering of an electron by a muon in the field of plane electromagnetic wave

“…Within the limits specified by conditions (40), (41) we can simplify expressions (7) - (14) for the amplitudes. In particular we can neglect the terms proportional to the parameter η e,µ in the expression for the matrixes G l−s,ν , G ν s (with the exception of the case of an ultrarelativistic electron that moves within a narrow cone with the photon from the external field), and the coefficients a ν e and a µ,ν (12) …”

“…Recently QED experiments in strong laser field have been actively started (e.g., [1,2]). Numerous problems are connected with the processes of interaction of the electrons with a nucleus and with each other in the strong laser fields [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Scattering of an electron by a nucleus in the light field was studied in detail for a long time (see, for example [3][4][5][6][7]), scattering of an electron by an electron (positron) in the light field was studied in the works [8][9][10][11][12][13][14][15][16].…”

Electron Scattering Processes in Non-Monochromatic and Relativistically Intense Laser Fields

“…Already in the 1990s, Denisenko and Roshchupkin [93] examined the Møller scattering in more complex laser fields under non-resonant conditions. In particular, they considered bi-chromatic linearlyor circularly-polarized plane wave fields and determined their influence on the laser-assisted process (see also [94]).…”

Parametric interference electron–muon scattering in the field of two pulse laser waves

“…The effects of an external field consisting of two monochromatic electromagnetic waves of different frequencies and amplitudes propagating in the same direction on the quantum processes of photon emission by electrons, pair production, and elementary particle decay are examined in [14][15][16][17][18][19][20][21][22][23]. The calculations using a quasi-monochromatic plane wave model to describe the short laser pulses can be found in [24][25][26].…”
