Phys. Rev. Lett. 77, 3518–3521 (1996)Wave Packet Isotope SeparationReceived 19 July 1996; published in the issue dated 21 October 1996 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 79Br2/81Br2 isotopes, that significant control over the isotope ratio can be achieved in a single shot. © 1996 The American Physical Society URL:
