Electrons from states with ni > 2 can return, initially, to the first-excited state (nf = 2), emitting one photon and then to the ground state emitting a second photon, with Eph = 10.2 eV, which is part of the Lyman series. Photons from transitions to the first-excited, (n = 2) state of the hydrogen ...

X-ray fluorescence
X-ray fluorescence (XRF) is the emission of characteristic ""secondary"" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
