Two-Center Integrals for r_{ij}^{n} Polynomial Correlated Wave Functions
  All integrals needed to evaluate the correlated wave functions with polynomial terms of inter-electronic distance are included. For this form of the wave function, the integrals needed can be expressed as a product of integrals involving at most four electrons.
