SPECTROCHIMICA ACTA PART B-ATOMIC SPECTROSCOPY, cilt.52, sa.2, ss.201-204, 1997 (SCI-Expanded)
Ll/L alpha intensity ratios were measured for elements in the atomic number region 57 less than or equal to Z less than or equal to 92. A 100 mCi Am-241 point source was used for excitation and a Si(Li) detector connected to a Nuclear Data (ND) 66 B multichannel analyser was used for counting. The experimental values were compared with theoretical values calculated using Scofield's tables based on the Hartree-Slater theory. These values were found to agree with each other.
