MoKand ULX-Ray Transitions from Separated Isotopes

Abstract
The Kα(KLIII, KLII) x-ray lines of Mo and the Lβ1(LIIMIV) and Lα1(LIIIMV) x-ray lines of U have been measured from separated isotopes using a double-crystal x-ray spectrometer. The x-ray transitions were induced by radiative excitation from a W target x-ray tube. Intensities were measured with a 70-cm Kr-filled Geiger counter.
