Phys. Rev. Lett. 103, 123001 (2009) [4 pages]Rydberg-State-Enabled Deceleration and Trapping of Cold Molecules
See accompanying Physics Viewpoint Hydrogen molecules in selected core-nonpenetrating Rydberg-Stark states have been decelerated from a mean initial velocity of 500 m/s to zero velocity in the laboratory frame and loaded into a three-dimensional electrostatic trap. Trapping times, measured by pulsed electric field ionization of the trapped molecules, are found to be limited by collisional processes. As Rydberg states can be deexcited to the absolute ground state, the method can be applied to generate cold samples of a wide range of species. © 2009 The American Physical Society URL:
