Self-Organization of Atomic Samples in Resonators and Collective Light Forces.
... The above measurements of phase jumps of the Bragg scattered light were performed with a stationary atom cloud. When the cloud is moving, as can be achieved by dropping the cloud for typically 20 ms before the pump is applied, we observe a strong modulation of the light emitted into the cavity at a ...

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.
