Valence photoelectron spectra of Na, K, Rb and Cs with s or p outermost electron: Evolution of the states from LS-coupling to jK-coupling

Abstract: The development of the fine structure of the and ( in Na, in K, in Rb, in Cs) configurations of alkali atoms ions from LS-coupling to jK-coupling has been studied by comparing the experimental photoelectron spectra with the results obtained with analytical LS-coupling and jK-coupling models.
