Arc Measurements of Fe I Oscillator Strengths
Abstract
Oscillator strengths for 534 lines of Fe i have been measured from a wall-stabilized arc. These lines have wavelengths between 2900 and 5800 A and cover a wide range in intensity and upper energy level. Lifetime values were used in normalizing to an absolute scale and in determining the arc temperature. This temperature agreed with that found independently, using LTE plasma diagnostics. Comparisons with other recent oscillator strength measurements generally show agreement within combined error estimates. Subject headings: abundances - spectra, laboratory - transition probabilities
