Helium is a colorless, odorless, elementary gas,He, with a specific gravity of 0.1368, liquefyingat –268.9°C, freezing at –272.2°C. It has avalency of zero and forms no electron-bondedcompounds. It has the highest ionization potentialof any element. The lifting power of heliumis only ...
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...
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...

The helium atom has two electrons bound to a nucleus with charge Z=2. The successive removal of the two electrons can be diagrammed as (9.1)He⟶I1He++e−⟶I2He+++2e−. The first ionization energy I1, the minimum energy required to remove the first electron from helium, is expe...
A second result of the present investigation is that more convincing evidence is given for the occurrence of neutralization during the violent collision by a non-Auger process. It is probable that this process, as well as the ionization process, results from an interaction between the helium ...
The helium isotopes 3He and 4He have long served as model systems for precision tests of theories of strongly interacting quantum matter and phase transitions for bosons, fermions, and mixed statistics systems. This has been spectacularly successful in two1 and three dimensions2, where the dynamics...
Spectroscopy of the 1S–2S transition in hydrogen-like helium (He+) would open a new route for tests of fundamental physics18,19,20. He+ has a doubly-charged nucleus, making its energy structure much more sensitive to higher-order Quantum Electrodynamic (QED) effects than hydrogen21 by at ...
