In this paper, we theoretically study the laser-induced modification of the vibrational parameters of a carbon dioxide molecule regarding its tunnel ionization. Our study predicts a 5% increase in the ionization rate in anti-Stokes channels that corr

We estimate theoretically the strong-field-modified vibrational parameters of three-atomic ABA molecules with D∞h symmetry in a laser-induced plasma. The linear CO2 and CS2 molecules in the X1Σg state are considered as examples. We show that doubl

We calculate double-differential cross sections of ultrasoft X-ray bremsstrahlung in electron scattering by Ar, Kr, and Xe atoms in the soft-photon approximation. The calculations are done for the isochromatic spectra (i.e., dependence on the electro

The choice of optimal calculation method for frequency-dependent polarizabilities (FDPs) is important for many applications. We compare some density functional theory (DFT) and ab initio methods with the quantum defect theory (QDT). Since QDT incorpo

The cross sections of ultra-soft x-ray bremsstrahlung in at electron scattering by Ar, Kr and Xe are theoretically calculated. The results are consistent with the absolute values of the differential cross sections measured by Gnatchenko et al [Phys.

We provide a short response to G Buica's comment on our paper 'Two-photon laser-assisted electron scattering on hydrogen atom'. The reply explains some of the points mentioned in the comment.

Synopsis The soft-photon approximation (SPA) is shown to give quantitative interpretation of absolute measurement of bremsstrahlung (BrS) cross section, σ, on atomic targets in the region of large wavelengths λ, for which σ∼ 1/λ2.

We consider a type of light-dressing effect in molecules which is due to laser-induced deformation of molecules. We derive general formulas which describe the change of the equilibrium bond lengths, bending angles, and vibration frequencies for a pol
