Parametrization of phase shifts in the muffin-tin approximation


In the present paper, a new parametrization variant is proposed that enables one, for a minimal number of experimentally determined parameters (one for the s, p, and d phase shifts in the case of nontransition elements), to describe with good accuracy the behavior of the phase shifts in a wide range of variation of the energy. The dependence of the introduced parameters on the chemical state of the considered center is investigated.
