Many Electron Atoms: Ionization Energies of Transition Elements

Many Electron Atoms: Ionization Energies of Transition Elements

The paper introduces a theoretical model aimed to calculate the ionization energies of many electron atoms and their ions. The validity of the model, which implements the statistical formulation of the quantum uncertainty to infer a simple formula of ionization energy, has been already proven in a previous paper comparing systematically experimental and calculated values for elements with atomi...

Ionization of many-electron atoms by a quasistatic electric field

We present a general expression for the field ionization probability of atoms and ions under a quasistatic external electric field. While the treatments available as yet are only for the case of a single electron in the outer nl subshell, the expression obtained here is applicable to atoms and ions with any number of electrons in the outer subshell and with partially filled inner subshell~s!. W...

Many-electron tunneling in atoms

A theoretical derivation is given for the formula describing N -electron ionization of atom by a dc field and laser radiation in tunneling regime. Numerical examples are presented for noble gases atoms. PACS numbers: 32.80.Fb, 87.64.Lg.

Theory of Electron Impact Ionization of Atoms

The theory of electron impact ionization of oneand two-electron atoms has advanced significantly in the past two years. This paper will summarize the progress that the members of our research center have contributed to.
