The calculation of continuum properties of Li-and Na-by a Green's function method

Abstract
Semi-empirical calculations of continuum properties of Li- and Na- are presented based upon the construction of an approximate Green's function for each system from a finite set of square-integrable functions. The results for photodetachment from the ground state of Li- and Na-, and for radiative decay from the 3Pe state of Na- are in harmony with calculations employing the Stieltjes imaging procedure and the photodetachment profiles are also in accord with close-coupling studies. The P-wave phase shifts for electron-alkali elastic scattering show good agreement with values from other theoretical calculations.
