Abstract

As a disagreement was found by Robinson1 between measured and calculated values for the ionization potential of Li+, I have made a direct calculation by the method described by Hylleraas2. The ionization potential in the 13th approximation is found to be 610,058 cm.-1. This result is in good agreement with the value 610,054 cm.-1 obtained from the Hylleraas' extrapolation formula for Z = 3.
