L'approximation de Born-Oppenheimer nous amène à chercher des solutions (approchées) de l'hamiltonien électronique (en unités atomiques) :
In this section we discuss the building up of atoms by the addition of more and more elec- trons to the appropriate nucleus whose only role to good
In the Hartee Approximation one assumes that the eigenstates of the total Hamiltonian can be written as a product of single particle states The variational
Our purpose in here is to formalize those kind of statements Therefore the question we would like to answer is “What is the best independent-particle
The Hartree-Fock approximation underlies the most commonly used method in chem- istry for calculating electron wave functions of atoms and molecules
