In our continuing study of correlation energies in both hetero- and ho
monuclear diatomics, contact is established here with the first-princi
ples study of S. Kais, S. M. Sung and D. R. Herschbach (1994, Int. J.
Quantum Chem., 49, 657) on atomic correlation energies. Their results
derive from renormalization of the large-dimension limit. Similarities
of scaling are revealed for light homonuclear diatomics.
