... A change in energy levels for a Rydberg atom in a circular state must obey selection rules so that ∆m = ±1 or 0, and ∆l = ±1. Thus an atom in a Rydberg state under guarded environmental condtions can only transition as n → n − 1, l → l − 1, |m| → |m| − 1 Thus a Rydberg atom approximates a two-level ...

... This is in agreement with Eq. (9) which can be seen after insertion of Eq. (6b) into Eq. (9) and replacing L by z. But again the problem arises that the law of energy conservation is violated, since the angular frequency of the propagating photon depends on z. However, within the particle picture, a ...

... Here, ~300 J of 800 nm light is frequency doubled using BBO to generate ~100 J of 400 nm light. BBO has a large nonlinearity and only modest beam walk-off, so it is a good choice for this application. The 400 nm light will serve as our pump, thus allowing us to generate light throughout most of t ...

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.
