A fully relativistic approach to calculating photoionization and photon-atom scattering cross sections for quasi one-electron atoms is presented. An extensive set of photoionization cross sections have been calculated for alkali atoms: lithium, sodiu

We reinvestigate a key process in electron-atom collision physics, the elastic scattering of electrons from helium atoms. Specifically, results from a special-purpose relativistic polarized-orbital method, which is designed to treat elastic scatterin

We have calculated the background energy ($V_0$) for positrons in noble gases with an \emph{ab initio} potential and the Wigner-Seitz (WS) ansatz. {\col In contrast to the general pseudo-potential approach, we have used accurate \emph{ab initio} pote

The distorted-wave and convergent close-coupling approaches are applied to positron-impact direct ionization of Li, Na and K. We find reasonable agreement between different theoretical approaches at higher energies; however, some significant discrepa

We present angle-integrated and angle-differential cross sections for electron-impact excitation of the (5s25p)P1/22→(5s26s)S1/22 transition in atomic indium. Experimental data for six incident electron energies between 10 and 100 eV are compared w

In previous papers we have proposed a method for the ab initio calculation of fully differential cross-sections for electron scattering in liquids and applied it to liquid argon, xenon and krypton. In this paper, we extend the procedure to the consid
