The spectroscopy process

Caption

The spectroscopy process: 1) The H2+ molecule is initially in its a state with weak vibration. 2) The spectroscopy laser wave irradiates the molecule. 3) When a photon is absorbed, the nuclear vibration is further excited, as is the rotation (indicated by dashed arcs). 4) A pulse of light is fired from a second laser. When a photon is absorbed, the molecule splits. 5) This generates a hydrogen atom and a free proton. This process reduces the number of molecules stored in the trap. The reduced number can be measured and serves as a signal for successful vibrational excitation. (Fig.: HHU/Magnus Roman Schenkel)
