The energy of a characteristic x-ray photon created when an L shell electron fills a Kshell 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 shell) equals 57.5.
