Explicitly correlated Gaussian functions with $ ; exp( -P62) factors have been used in variational calculations of the ground state of the helium atom. Additional correlation factors in the form of even powers of rii were introduced to the Gaussian functions with exponential correlation components b

## 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
