Among the methods that may be used to carry out multicenter integrals over STOS, the one‐center two‐range expansion is probably the oldest one. However, the convergence of the leading series is generally slow and, hence, time‐consuming. Therefore, it was the aim of the present work to show that the so‐called nonlinear sequence transformations may be of substantial help for improving the rate of convergence of such series. © 1994 John Wiley & Sons, Inc.
