Dynamic polarizabilities and Van der Waals coefficients for the ground 2 2S and excited 2 4Po states of Li
Résumé
The dynamic dipole polarizabilities at real and imaginary frequencies have been determined for the ground 2 2S and excited 2 4Po states of Li using our time-dependent gauge-invariant method. Accurate C6 dispersion energy coefficients for the Li(2 2S)-H2 and Li(2 Po4)-H2 systems and their dependence on the intramolecular H-H distance are reported. © 1994 The American Physical Society.
