摘要：

We introduce and demonstrate a general wave packet method for laser isotope separation. In this scheme, laser excited molecular (or atomic) wave packets of differing isotopes become spatially separated in the course of their long-time free evolution. In order to overcome the quantum spreading of wave packets, we make use of the phenomenon of revivals. We demonstrate experimentally, with mixed Br-79(2)/Br-81(2) isotopes, that significant control over the isotope ratio can be achieved in a single shot.
