Add to ORKGAbout a year ago, R.T. Birge [1] suggested the possibility of an experimental determination of the fine structure constant based on measurements of the x-ray spin doublet splitting (LII-LIII levels). A direct determination of this quantity is of interest because of the discrepancies existing in the values of the atomic constants, and because of controversial ideas as to the value of this constant itself
