Projections of the atomic structure around Nb atoms in a LiNbO(3) single crystal were obtained from a white-beam X-ray absorption anisotropy (XAA) pattern detected using Nb K fluorescence. This kind of anisotropy results from the interference of X-rays inside a sample and, owing to the short coherence length of a white beam, is visible only at small angles around interatomic directions. Consequ...
We report the observation of polarization anisotropy in the optical suppression of photoassociative ionization (PAI) collisions. Binary collisions occur within a tightly collimated and optically cooled velocity group of a single sodium beam. A laser beam, blue-detuned with respect to the atomic resonance transition, crosses the atomic beam and suppresses the PAI rate. We measure this suppressio...
Laser cooling and trapping offers the possibility of confining a sample of radioactive atoms in free space. Here, we address the question of how best to take advantage of cold atom properties to perform the observation of as highly forbidden a line as the 6S-7S Cs transition for achieving, in the longer term, Atomic Parity Violation measurements in radioactive alkali isotopes. Another point at ...
