摘要
As shown by Koide, the dispersion energy can be written in terms of wave number and frequency dependent polarizabilities. His result is here combined with the Hellmann-Feynman theorem to express the deformation of the atomic density at large separation in a homonuclear diatomic molecule in terms of these polarizabilities. The Gurney-Magee wave function for H-2 is given as an example of an approximate procedure to treat such a deformation in a simple, compact way.
