Ion-collision broadening of solar lines in the far-infrared and submillimeter spectrum
Abstract
The authors give new theoretical data for calculating the ion impact broadening of solar far-infrared and submillimeter lines. These are more accurate than, and should be preferred to data extrapolated directly from Griem's (1967) work on radio recombination lines. The variation of the line width as a function of the upper level of the transition has also been investigated. It may be a potentially important diagnostic tool for determining the physical conditions in the solar atmosphere.
