摘要：

We have imaged an 18 mu K cloud of Rb-85 atoms bouncing freely on a horizontal, concave magnetic atom mirror (radius of curvature R). A high-quality image is observed even after 14 reflections. Initially compact, the cloud is alternately collimated (odd bounces) and brought back to a focus (even bounces) when dropped from a height R/4. This multiple reconstruction of a thermally expanding cloud hinges on the microscopic reversal of the atomic motion. We ddiscuss the factors limiting the resolution of the mirror and describe the method of construction. [S0031-9007(98)08251-9].
