Abstract

We have calculated the 1¹S, 2¹S, and 2³S state energies of helium atom described by the nonrelativistic Schrodinger equation, and obtained (in atomic units): E(1¹S) equals -2.9037243770330010, E(2¹S) equals -2.1459740460540720, E(2³S) equals -2.1752293782367900. We have estimated the relative accuracy of the order of 10^-12 minus 10^-13 for the 1¹S and 1²S states, and 10^-15 minus 10^-16 for the 2³S state. The importance of calculations of helium for high resolution laser spectroscopy is emphasized.
