The Philosophy and Strategy for STO Integral Evaluation Using the C-Matrix Algebraic Single-Center as into appropriate Taylor series. The policy of carrying out all algebraic manipulations by computer and using different formulas for different ranges of parameters re-establishes the use of formulas for integral evaluation after the abandonment of this approach many years ago.

Slater.. These functions may then properly be called orthonormal Slaters (ONSs). The radial parts may be constructed, as Slater points out, by an analytical Gram-Schmidt process from the minimum n-quantum number, normalized radial Slaters.

lude the power series expansions for small arguments, and continued-fraction or asymptotic expansions for large arguments.. None of these methods are fast for a large intermediate argument range, and the integrals are often evaluated by finite numerically fitted Chebyshev. or rational-fraction. expansions.

integration variables are to be defined with respect to one common center. Therefore, it is necessary to express all those exponential-type functions (ETF’s) and operators, which occur in the integrand, with respect to the chosen fixed reference system of integration. This causes serious problems b
