Maybe this paper researching some arcane from the POV of PhysicalChem would be useful?

Pablo Mtz

In the case of limited resources, I'd instead suggest density-functional-based tight-binding semi-empirical calculations, check its availability for metals here:

If it is not available in G09, you may try Orca.

Best, Pablo
