Research Abstract

The Dirac Equation (DE) is one of the most important equations in the relativistic quantum chemistry. The DE for one electron systems is composed of four components. If we can remain only the electron states and annihilate the positron states from the DE, it becomes less complex equation. In this study, we annihilated the positron states from the DEs of the hydrogen-like atoms and hydrogen molecular ion. The annihilated equations were exactly solved with the Free Complement method. We have derived the General Coalescence Conditions, which is the necessary conditions for wavefunctions when two particles come close with each other.
