Rayleigh scattering off a Bose-Einstein condensate was studied. Exposing an elongated condensate to a single off-resonant laser beam resulted in the observation of highly directional scattering of light and atoms. This collective light scattering is caused by the coherent center-of-mass motion of the atoms in the condensate. A directional beam of recoiling atoms was built up by matter wave amplification.
研究了玻色-爱因斯坦凝聚体的瑞利散射。将拉长的凝聚体暴露于单个非共振激光束下,观察到了光和原子的高度定向散射。这种集体光散射是由凝聚体中原子的相干质心运动引起的。通过物质波放大形成了反冲原子的定向束。
