摘要: The weighted orthonormality relations for many-particle Sturmian basis functions are derived both in momentum space and position space. It is shown that when these used as a basis, the kinetic energy term disappears from Schrodinger equation. A general method developed constructing many-electron sets one-electron Sturmians. This illustrated by applications to atoms ions H2 molecule. direct solution of equation using Sturmianbasis offers useful alternative Hartree–Fock approximation configuration interaction; it leads an automatic optimization orbital exponents.
