Abstract

Fluorescence ( omega ₂), Auger (a₂) and Coster Kronig (f₂₃) L_II subshell yields in thorium have been determined from measurement of LX-rays emitted following alpha decay of ²³²U. alpha -X coincidences techniques, employing a surface barrier detector for the alpha particles and NaI(Tl) scintillation counter for LX-rays, were used to measure the total fluorescence yield omega _L of the L shell in ²²⁸Th. The relative intensity of the LX photons from the L_II and the L_III subshells was determined with a Si(Li) LX-ray spectrometer. The experimental results are: omega ₂=0.44+or-0.03; f₂₃=0.13+or-0.10; a₂=0.43+or-0.10, and omega _L=0.46+or-0.03.
