Widths of some L X-ray lines of iridium, platinum, gold, thorium and uranium

Abstract

X-ray L alpha 1, L alpha 2, L beta 1, L beta 2, L beta 33, $L gamma 1 and Ll line widths of elements with Z=77, 78, 79, 90, 92, have been measured using a 50 cm radius quartz crystal spectrometer and a NaI(Tl) scintillation counter together with a photographic plate. The spectra were analysed by means of computational techniques and the experimental results are compared with the theoretical predictions.
