Hydrogen and the Central Force Problem
... We thus have a partial differential equation which is traditionally solved using separation of variables. The separation of variables would be trivial if V (x1 , x2 ) = V1 (x1 ) + V2 (x2 ) since we just have a diffiQ in x1 added to a diffiQ in x2 . This would be the situation if particle 1 and 2 moved in ...

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.
