Abstract Non-thermodynamic equilibrium calculations to determine the relative concentration of the various stages of ionization of the elements from H to Fe are presented. The results are derived from statistical equilibrium equations for simplified atomic models containing only a ground state and continuum for each stage of ionization. Calculations are given for an electron temperature range of logio T(ev) = -0.5 to 3.0. In general, the calculations apply for an electron density n, < 10 . In many cases they are valid for high densities, n, = 1016 or 10 . A table is given which allows one to determine the upper-limIt of n, for any specific case. The same table illustrates the value of n, required before local thermodynamic equilibrium would be valid.
