Abstract
Photoionization cross sections have been calculated by means of the Scaled-Thomas-Fermi method for the alkali metals and the alkaline earths. Using these results the absorption coefficients for bound-free transitions have been obtained for thermal plasmas of 6000 to 20,000 K and wavelengths from 500 to 10,000 Å. In addition the oscillator strengths are given for the principal series of the alkali metals.
