Atoms with a Single Valence Electron,een carried on for a long time, starting from the discovery of absorption lines in the solar spectrum by Fraunhofer in 1817. These studies have resulted, over the years, in the emergence of a new discipline of experimental and theoretical physics that is called spectroscopy. This discipline had a fu

Term Energies,ntral field approximation: a zero order Hamiltonian whose eigenvectors, in general degenerate, are the states belonging to the different configurations, and a “corrective” Hamiltonian containing various terms including, in particular, the Coulomb repulsion between electrons. By neglecting the intera
