V. Magnasco et al., ONE-CENTER CUSPED GAUSSIANS CALCULATION OF H(1S)-H(1S) DISPERSION COEFFICIENTS, Gazzetta chimica italiana, 125(7), 1995, pp. 319-322
Use of a limited set of cusped Gaussians, namely GTO especially devise
d to satisfy the nuclear cusp condition, allows for the remarkably acc
urate one-centre calculation of H(1s)-H(1s) dispersion coefficients.
