Savin partitioning #79

Open susilehtola opened 12 months ago

susilehtola commented 12 months ago

In Int. J. Quantum Chem. 34, 55 (1988), Savin employs a partitioning where the atomic weight is given by

$$ w_A({\bf r}) = z_A \zeta_A^3 \exp(-\zeta_A r) $$

where $\zeta_A = Z_A$ "is a reasonable choice".

This partitioning is already available in CRYSTAL.
