The Crucial Role of Kinetic Energy in Interpreting Ionization Energies
Frank Rioux and Roger L. DeKock
St. John's University / College of St. Benedict, Department of Chemistry, 37 South College Avenue, St. Joseph, MN 56374-2099

May 1998
Vol. 75 No. 5
p. 537
Abstract
The experimental ratio of the ionization energies of H and He is 1.81. We show that it is not correct to interpret this ratio using a classical Coulombic potential energy model. Rather a quantum mechanical model is required in which both kinetic and potential energy play a role.
