摘要:
The connection between local-energy functions and the integral Hellmann-Feynman (IHF) method is discussed. Richardson and Pack's method of partitioning the Hamiltonian is related to local energies and their numerical results are rationalized. It is shown that local-energy concepts can be useful in choosing the best from among the many possible IHF calculations for a process. IHF calculations already in the literature are analyzed from this standpoint. Calculations on HeH+ are reported which indicate that the IHF method may be particularly useful for shorter one-center expansions.
