Abstract
Atomic one-electron energies and associated radial orthogonalized wavefunctions are calculated with the variational method. The potential field was a universal one and the trial functions were taken as linear combinations of Slater-type orbitals. The exponents were determined by a geometrical series which are sometimes called “even-tempered” exponents [1]. Energies, linear coefficients, exponents are tabulated for Li, O, Cr, Cu atoms, respectively. The agreement with the experimental results and other theoretical ones is good.
