... be the spin up and down wave function for a single electron .(SZ is diagonal) Write down all the possible spin wave functions of the system in terms of the single particle wave function such that the wave funstions are eigenstates of the total spin and its z-component in terms of α and β. 7. The rel ...

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.
