Measurement of partial L fluorescence yields of bismuth using synchrotron radiation

Tunable monochromatic photon radiation was used to measure transmission of a bismuth target in the energy range from 7 keV to 20 keV. Partial L fluorescence yields of bismuth were obtained by combining measurement of the fluorescence induced by photoionization of the bismuth target and X-rays from the radioactive decay of 210Pb. Several photon energies have been used to successively ionize the L subshells, which allowed detailed analysis of the rearrangement spectra and determination of the X-ray relative intensities of the L1, L2 and L3 series.
