Long-range interactions of two Li atoms and a Li ion
ORAL
Abstract
A classic application of high-precision wave functions obtained using
variationally optimized basis sets is to calculate
coefficients appearing in the long-range potentials for atom-atom interactions.
While similar methods have been applied to the case of three ground state atoms,
applications to the case of two atoms and an ion are rare.
Here we summarize our results for two Li atoms and a Li ion, where, using
perturbation theory and highly accurate wave functions calculated variationally in Hylleraas coordinates, long-range potentials were obtained [Phys. Rev. A 104 (2021) 022807; 101 (2020) 032702].
