Abstract
The advantages of the absorption method for the measurement of relative oscillator strengths, as used at Oxford, are discussed and improvements made recently in the technique are described. Using the method, relative oscillator strengths have been measured for 16 low excitation potential lines of Fe 1, and a photometric scale covering nearly six decades set up. The accumulated probable error over these six decades is about 5 per cent. A critical comparison is made with the results of other methods of measurement and with the results of calculation.Keywords
