✦ Synopsis
Slater transform functions have been used variationally to approximate the helium atom ground state. The results are significantly betl:r than either a scaled gaussian or x scaled exponential and the energy is very close to the Hartree-Fock value.

The electronic energy of atoms and molecules may be evaluated accurately by the use of wave functions where the interelectronic distances are explicitly present. In particular, explicitly correlated Gaussian-type functions make these types of calculations feasible and computationally tractable even
## Abstract Explicitly correlated Gaussian functions have been used in variational calculations on the ground state of the helium atom. The major problem of this application, as well as in other applications of the explicitly correlated Gaussian functions to compute electronic energies of atoms and
The properties of the long-range part of the previously suggested generalized potential energy function and Coulomb-subtracted generalized potential energy function have been investigated. It is demonstrated that these empirical functions can correctly reproduce the long-range part of the diatomic p
Roothaan-Hartree-Fock (RHF) calculations have been carried out for the ground states of the atoms from helium to krypton using certain exponential-type functions, the Ꮾ functions. We report a compilation of single-and double-zeta (SZ and DZ) wave functions. A comparison with the conventional SZ and
We advance a reformulation of the Hartree᎐Fock problem in the context of the local-scaling transformation version of density functional theory. Explicit functionals of the energy are obtained. These functionals are expressed in terms of both the one-particle density and the local-scaling transformat
