The electron-impact ionization of lithium-like ions C3+, N4+, O5+, Ne7+, and Fe23+ is studied using a combination of two-potential distorted-wave and R-matrix methods with a relativistic correction. Total cross sections are computed for incident ener

Relativistic impulse approximation (RIA) has been widely used in atomic, condensed matter, nuclear, and elementary particle physics. In former treatments of RIA formulation, differential cross sections for Compton scattering processes were factorized

Photoionization cross section $\sigma_{n\kappa}$, asymmetry parameter $\beta_{n\kappa}$, and polarization parameters $\xi_{n\kappa}$, $\eta_{n\kappa}$, $\zeta_{n\kappa}$ of Xe and Rn are calculated in the fully relativistic formalism. To deal with th

In this paper, we calculate relativistic photoionization parameters for Mg and Mg-like ions for photon energies between 10 eV and 30 keV using Dirac–Fock initial discrete-state wave functions and final central-field continuum wave functions. By tak
With plasma shielding effects of the Debye-H\"uckel model, we investigate the relativistic photoionization processes of H, Nb$^{40+}$ and Pb$^{81+}$ plasmas in the H-isoelectronic series. The shielded nuclear potential of Yukawa-type experienced by t

Starting from the relativistic equation of motion governing quantum collision processes, we shall formulate the relativistic quantum collision theory in an ab-initio manner. Quantum electrodynamic effects are, however, incorporated perturbatively. Be
