characteristic rays

characteristic rays
x-rays emitted as a result of the rearrangement of electrons in the inner shells of atoms, as when electrons are ejected from the inner shells by high-speed bombarding electrons or when an orbital electron is captured by the nucleus during radioactive decay; the wavelengths of the rays produced depend on the element and the energy levels involved. Cf. characteristic fluorescent r's.
