Electron–ion collisions are among the most important atomic processes in ionized gases.
They comprise elastic scattering, excitation, ionization, and recombination. Theoretical …

The interaction of ionising radiation with atoms and ions is a key fundamental process. This
report concentrates on studies of photoexcitation/photoionisation using laser-produced …

Using complex scaling and a correlated basis constructed in terms of B splines, we calculate
the Li+ photoion yield in the presence of a laser-induced coupling between the triply excited …

Hollow atoms in which the K shell is empty while the outer shells are populated allow
studying a variety of important and unusual properties of atoms. The diagram x-ray emission …

Double-K-shell-vacancy production in Li by 95 MeV/nucleon Ar 1 8+ projectiles was
investigated using high-resolution electron spectroscopy. The two K vacancies are found to …

The photoion Li 2+/L i+ production cross section ratio of ground-state atomic lithium has
been measured for photon energies ranging from 80 to 424 eV. The absolute cross sections …

We present new results for the doubly excited states Li+(nlnl) of singly ionized lithium which
arise from the measurements of the Auger decay of these states to Li++ ground state ions …

New measurements of photoionization cross-sections of the lithium isotopes are reported
employing a Time of Flight (TOF) mass spectrometer in conjunction with an atomic beam …

A computational method for calculating the hyperspherical adiabatic potential curves for
three-electron atomic systems is presented. This method allows us to obtain accurate …

We have measured the angle-resolved energy dependence of the electrons emitted over the
energy range of the triply excited 2 s 2 2 p P 2 lithium resonance using synchrotron …
