of ionization potentials in eV, and number density, partial pressure, and per cent of U0, U , U1+, . ., U12 ,and electrons.

        The theoretical ionization potentials used by the program are values which were calculated by J. T. Waber, D. Liberman, and D. T. Cromer (75). These values follow in Table 2.
