摘要：

This paper presents the coronal ionization state distribution for argon. The calculations include ab initio rate coefficients for collisional excitation followed by autoionization (EA), and rates for direct ionization and dielectronic and radiative recombination. The EA rate coefficients have been fitted to analytical expressions, and the fitting coefficients are tabulated. The paper then presents the calculated radiative cooling coefficient for argon ions in a low-density plasma as a function of temperature. The channels for power loss from argon ions include collisional-radiative (CR) line emission, dielectronic and radiative recombination, and bremsstrahlung emission. The power emitted via CR line emission for each ion is tabulated on a grid of temperatures and densities. The total power loss coefficient is fitted to an analytical expression in powers of the temperature. (C) 1998 Academic Press.
