The nonrelativistic ionization energy levels of a helium atom are calculated for S, P, D, and F states. The
calculations are based on the variational method of “exponential” expansion. The convergence of the calculated
energy levels is studied as a function of the number of basis functions N. This allows us to claim that the obtained
energy values (including the values for the states with a nonzero angular momentum) are accurate up to 28–35
significant digits.
