Energy-dispersive measurements of the K alpha 3, KM1, K beta 1, and K beta 2 x-ray intensities relative to the K alpha 1 intensity in lead and uranium.

Lead and uranium K x-ray spectra recorded with a specially designed Ge detector have been fitted using an accurately determined line-shape model. This provides the first accurate Ge measurements of the K..alpha../sub 3/ relative intensity and the first reported measurement of the KM/sub 1/ relative intensity. Measurements of the transition probabilities of K..beta../sub 1/ and K..beta../sub 2/ relative to the K..alpha../sub 1/ line provide a much more stringent test of calculated overlap and exchange effects than earlier ratios of gross line groups.
