Convergence accelerators in the computation of molecular integrals over Slater-type basis functions in the two-range one-center expansion method

The so-called nonlinear transformations may be of substantial help in many practical problems including the so-called multicenter integrals. In this work Wynn's epsilon algorithm and the Levin's u transformation have been used to improve the convergence of the series representation of three-center two-electron integrals obtained via the so-called two-range one-center expansion method
