Observation of quantum capture in an ion-molecule reaction
Katharina Höveler, Johannes Deiglmayr, Josef A. Agner +3
In 1954, Vogt and Wannier (Phys. Rev. 95, 1190) predicted that the capture rate of a polarizable neutral atom or molecule by an ion should increase by a factor of two compared to t…
Precision measurement of the ionization energy and quantum defects of 39K I
Michael Peper, Felix Helmrich, Jonas Butscher +4
We present absolute-frequency measurements in ultracold 39K samples of the transitions from the ground state to np Rydberg states. A global nonlinear regression of the np1/2 and np…
Fluorescence-lifetime-limited trapping of Rydberg helium atoms on a chip
Valentina Zhelyazkova, Matija Žeško, Hansjürg Schmutz +2
Metastable (1s)(2s) helium atoms produced in a supersonic beam were excited to Rydberg-Stark states (with in the range) in a cryogenic environment and sub…
