Excerpt from The Application of Wave Functions Containing Interelectron Coordinates: I. The Ground State Energy of Lithium
The second thing done in applying swf was to devise an accurate approx imation method to integrate functions containing three or more interelectron coordinates over the space of the nuclear coordinates (including angles). In Section 4 an accurate approximation method is described which consists of expanding the functions containing the interelectron coordinates about well-chosen points in the space of the nuclear coordinates. The approx imation technique is tested in helium-like systems and is found to be better than 99 3q> accurate.

Paperback. Condition: New. Print on Demand. This book presents a new approach to describing atomic systems by introducing interelectron coordinates explicitly. The simplest atomic systems are treated, and excellent results are found in calculating the energy values of the corresponding ground states. In addition, an approximation technique of high accuracy has been developed to handle, mathematically, wave functions containing interelectron coordinates. The new wave function proposed in this book describes the nuclear coordinates as particles filling the bound energy levels in pairs, while the interelectron coordinates are described as particles all piling into the lowest energy continuum state. This significantly improves upon existing methods, and demonstrates how interelectron effects can be taken into account to a very significant extent.
