In some of the early studies, the pseudospinors were obtained by minimizing a function involving the kinetic energy (Kahn et al. 1976). The shape-consistent pseudopotentials of Hay and Wadt (Hay and Wadt 1985, Wadt and Hay 1985) and Christiansen, Ermler, and coworkers (Pacios and Christiansen 1985, Hurley et al. 1986, La John et al. 1987, Ross et al. 1990, 1994, Ermler et al. 1991) are obtained by fitting a polynomial function to the core tail with the requirements that it have no nodes and the minimum number of inflection points and must match the derivatives to the order of the polynomial at the join point. While this procedure guarantees the smoothness of the function, especially after the pseudospinor is expanded in a Gaussian basis set, the choice of the join point must be made with care. If it is too far out, the results can be unsatisfactory, as was found for the 6p elements (Wildman et al. 1997).
