ON DIRECTLY SOLVING RADIAL SCHRÖDINGER EQUATION FOR THE GROUND STATES OF TWO ELECTRON ATOMS OR IONS BY GENETIC ALGORITHM
Rajendra Saha, Sukhamoy Bhattacharyya · Journal of Theoretical and Computational Chemistry · 2004
A recipe is proposed for solving the radial Schrödinger equation (SE) for two electron atoms and ions in their ground states by genetic algorithm (GA). The recipe is tested for the isoelectronic series of H -, He , Li +, Be 2+ atoms and ions. The strong and weak features of the method are analyzed, and possible directions of improvement suggested.
