Properties of Copper Plasma. Calculation of the Partition Function, Species Concentration, and Spectral-Line Intensities

摘要

The self-consistent partition, ionization potential lowering, electron, ion, and neutral particle species concentrations, and the absolute spectral-line intensities of Cu I Lambda 5106 and Cu I Lambda 5153 are reviewed and tabulated for pressures between 0.03 and 10 atm, for original mole fractions between 10-4 and 0.03 and for temperatures from 2000 to 10,000 K, for copper vapor in a hot inert gas at thermal equilibrium. Only single ionization of copper is considered in this range of conditions. For the partition function cutoff, all electron states whose classical semi-major axis exceeds one-half the Debye distance are suppressed. The results should be of use in spectroscopic plasma diagnostics and other situations where the trace amounts of copper usually present can be for temperature measurement. (Author)
