Precision measurement of relative oscillator strengths - VI. Measures of Fe I transitions from levels a5 F1-5 (0.86-1.01 eV) with an accuracy of 0.5 per cent.
Abstract
Measurements of relative oscillator strengths are reported for 68 lines of Fe I with excitation potentials of 0.86 to 1.01 eV and originating from the levels a5 F(1-5). Evidence is presented to show that the accuracy of these measurements is about 0.5%. The relative measures are placed on an absolute scale (with an accuracy of 2.6%) by relating them to the absolute oscillator strength of the 371.994-nm line. The results are compared with previous laboratory data.
