The effect of an external magnetic field on L x-ray intensity ratios for elements in the range 73 ≤ z ≤ 92 at 59.54 keV

The L shell x-ray intensity ratios L alpha/Ll, L alpha/L beta, and L alpha/L gamma for Ta, W, Au, Hg, T1, Pb, Bi, Th, and U have been measured using the 59.54keV incident photon energy in the external magnetic field of intensities +/- 0.15, +/- 0.45, and +/- 0.75T. A comparison is made of the experimental values obtained for B = 0 with calculated values using theoretical x-ray emission rates, subshell ionization cross sections, subshell fluorescence yields and Coster-Kronig transitions probabilities. In the absence of external magnetic field, a fairly agreement is observed between experimental and theoretical values.
