The central-field configurational model

摘要: In the central-field configurational model, basis functions of atomic states are products a radial part, an angular and spin part. They must obey antisymmetry principle. can be gathered into electronic configurations. The (wavefunctions) eigenvectors H Hamiltonian, which is essentially sum kinetic energies, electrostatic interactions between nucleus electrons, those plus magnetic orbital moments electrons. obtained by diagonalizing over single configuration (in intermediate coupling), or several configurations interaction). (3p 2 + 3d 2) mixing taken as example.
