Abstract
The use of a continuum source in conjunction with a piezoelectrically scanned Fabry-Perot interferometer is described for the observation of absorption line-widths of the calcium 422.67 nm line in hydrogen diffusion flames. The variation of the observed absorption half-width with calcium concentration has been examined. Values for the effective and collisional half-widths for the Ca absorption line are given, and the corresponding a-parameters and collisional cross sections are calculated.Keywords
