Characteristic K-series, L-series, etc. x-ray photons are produced when the atoms are excited to ionize a K-shell electron of the atom. The generation of such a K-hole state followed by K-, L-series emissions from the element unambiguously identity the element. The initial K-hole state of excitation can be done either by electron bombardment or photon bombardment. The results presented here are due to photon bombardment. The simplicity of the instrument and its application to know the presence of trace elements in geological and biological samples of normal and abnormal tissues is an attractive feature.
