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…
New method to study ion-molecule reactions at low temperatures and application to the H + H H + H reaction
Pitt Allmendinger, Johannes Deiglmayr, Otto Schullian +4
Studies of ion-molecule reactions at low temperatures are difficult because stray electric fields in the reaction volume affect the kinetic energy of charged reaction partners. We…
Infrared spectroscopy of molecular ions in selected rotational and spin-orbit states
Ugo Jacovella, Josef A. Agner, Hansjürg Schmutz +2
First results are presented obtained with an experimental setup developed to record IR spectra of rotationally state-selected ions. The method we use is a state-selective version o…
