The present method yields results that are far better, in convergence, stability and precision, than any other momentum space method. Accurate result is obtained for the atomic exponential (Yukawa) potential with an estimated error of less than 1 in 1015 (1010) after some 13 (10) iterations.595-600engArtigo10.1016/0009-2614(96)00710-5WOS:A1996VD44100011Acesso restrito2-s2.0-0030598791
