Abstract
AbstractUsing integer and noninteger n‐Slater type orbitals in single‐ and double‐zeta approximations, the Hartree‐Fock‐Roothaan calculations were performed for the ground states of first ten cationic members of the isoelectronic series of He atom. All the noninteger parameters and orbital exponents were fully optimized. In the case of noninteger n‐Slater type orbitals in double zeta basis sets, the results of calculations obtained are more close to the numerical Hatree‐Fock values and the average deviations of our ground state energies do not exceed 2×10−6 hartrees of their numerical results.
