Abstract
- Convergence of dipole pseudospectra for the 2-electron model systems He and H 2 is studied for Riley–Dalgarno- and Kolos–Wolniewicz-type wavefunctions explicitly including electron correlation in terms of positive powers of the interelectronic distance. 40-term pseudospectra for He and 34-term for H 2 give almost a 4-figure accuracy for the static polarizabilities of the monomers and the resulting C 6 dispersion coefficients of the dimers.
