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…
The role of Coulomb anti-blockade in the photoassociation of long-range Rydberg molecules
Michael Peper, Martin Trautmann, Johannes Deiglmayr
We present a new mechanism contributing to the detection of photoassociated long-range Rydberg molecules via pulsed-field ionization: ionic products, created by the decay of a long…
Photodissociation of long-range Rydberg molecules
Michael Peper, Johannes Deiglmayr
We present photodissociation of ultracold long-range Rydberg molecules as a tool to characterize their electronic properties. We photoassociate K2 37P molecules with highly entangl…
Heteronuclear long-range Rydberg molecules
Michael Peper, Johannes Deiglmayr
We present the formation of homonuclear Cs2, K2, and heteronuclear CsK long-range Rydberg molecules in a dual-species magneto-optical trap for 39K and 133Cs by one-photon UV photoa…
Formation of ultracold ion pairs through long-range Rydberg molecules
Michael Peper, Johannes Deiglmayr
We propose a new approach to excite ion-pair states of ultracold dimers. The central idea is a two-step process where first long-range Rydberg molecules are formed by photoassociat…
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…
