New laser‐induced fluorescence method for molecular beam velocity analysis

We have measured the velocity distribution of a Na2 supersonic beam by a time of flight method in which a chopped beam from an argon ion laser depopulates a single vibration–rotation level of the Na2 ground electronic state, and a continuous laser beam further downstream is used to detect the arriva...

Beschreibung
Zusammenfassung:	We have measured the velocity distribution of a Na2 supersonic beam by a time of flight method in which a chopped beam from an argon ion laser depopulates a single vibration–rotation level of the Na2 ground electronic state, and a continuous laser beam further downstream is used to detect the arrival of the tagged molecules by observation of changes in the laser‐induced fluorescence.
