Abstract : The photoionization cross section of argon and krypton was measured in the 100 to 300 angstrom range. A shallow minimum was found at 270 angstroms, in agreement with a calculation by Cooper. For krypton, the M4,5 edge was found at about 133 angstroms in agreement with the findings of Codling and Madden. For argon, several sum rules on the oscillator strengths were evaluated. Excellent agreement was found for the Thomas-Reiche-Kuhn sum rule. For the sum rules in 1/E and 1/Esq, the agreement with experiment was poor. This is attributed to a lack of experimental values for the oscillator strengths of the discrete transitions. (Author)
