An investigation of oscillator strength calculations for interstellarlines of CL I.
Abstract
Recent oscillator strength calculations for the 1088.062, 1097.369 and 1347.240 A interstellar lines of Cl I by Ojha and Hibbert (1990) are found to be incompatible with high quality Copernicus observations. Possible explanations are discussed, including severe blending in the observational data, and misidentification of the 1088.062 and 1097.369 A transitions. Until these discrepancies are resolved, column densities deduced from these two transitions should be treated with caution.
