The ground-state energy of the helium atom in a plasma is calculated by the variational method with the static screened Coulomb potential as the interparticle potential. This is used to calculate the ionization energy of the helium atom as a function of the screening parameter. The critical value...

The ionization cross sections for He and Ne atoms and Nmolecules on impact with He atoms have been measured over the laboratory energy range from 30 to 1000 eV. The incident atomic He beam was produced by the technique of ionization by electron impact, electrostatic acceleration, and neutralizati...
In excitation — autoionization the helium atom makes a transition to an unstable doubly excited bound state He**(nl, n′l′) (nl ≠ ls, n′l′ ≠ 1s), ie, a resonant state of the atom, which then ejects an electron leaving a residual He + ion. The particular case we consider ...
We calculate analytically the cross sections for ionization of the helium atom with absorption and scattering of high-energy photons. The electrons are assumed to be moving in the Coulomb field of the nucleus. The electron-electron interaction is taken into account in the first order of perturbatio...
Electron affinities are smaller values than ionization energies. This puts the trend in electron affinity moving across a period into perspective. Rather than a net release of energy when an electron is gain, a stable atom like helium actually requires energy to force ionization. A halogen, like...
