ARRT registry exam graded A UPDATE NEW!! The energy of a characteristic x-ray photon created when an L shell electron fills a K shell vacancy in a tungsten atom will have which of the following energies? a. 69.5 keV b. 57.5 keV c. 91.5 keV d. 12 keV - Answer b. 57.5 keV The energy of characteristic photons is determined by the difference in binding energies between the two electron shells involved in the process, which in this question are K and L shells. 69.5 (K shell) minus 12 (L sh...
