Ll, L-alfA,L-beta and L-gamma X-ray fluorescence cross sections for Ce, Pr and Sm excited by Y K-alfa and Mo K-alfa X-ray photons

Ll, L alpha, L beta and L gamma x-ray fluorescence cross-sections were measured for Ce, Pr and Sm at excitation energies of 14.94 and 17.44 keV using a low-energy Si(Li) detector coupled to a model 1024 computerized multi-channel analyser, Experimental results are compared with the theoretical estimates of Chen et al, based on relativistic Dirac-Hartree-Slater theory, Good agreement was observed between the experimental and theoretical values
