Abstract
A method of calculation of interatomic interaction potentials in the presence of ionized states has been developed. They have been obtained for the atoms with different ionization degree on example of aluminum. The Heine-Abarenkov-Animalu model potential form factors was employed. The form factor parameters of ionized atoms was determined on the base of the quantum defect method using the atomic-spectroscopy data. The potential of interatomic interaction for different charged states with different degree of ionization were determined.
Highlights
It is known that intensive radiation generates ionized atoms within the track of a fast charged particle as well as near the solid surface
The knowledge of corresponding potentials of interatomic interaction is necessary for studying the behavior of partially or entirely ionized matter
Calculations were based on the method of pseudopotentials using Heine-AbarenkovAnimalu model potentials with parameters which were determined from spectroscopic terms of free ions following the method of quantum defect
Summary
It is known that intensive radiation generates ionized atoms within the track of a fast charged particle as well as near the solid surface. Calculations were based on the method of pseudopotentials using Heine-AbarenkovAnimalu model potentials with parameters which were determined from spectroscopic terms of free ions following the method of quantum defect. Where Z is the ion-core charge, δnl and Δnl denotes quantum defects characterizing the |Ze|–charge induced deviation of an atomic potential in such a configuration of inert gas shells from a Coulomb ones.
