Functions & Applications

This crossed beam machine is built for the simplest chemical reactions involving H-atom or D-atom as one of the product, for example H+H2→H2+H, F+H2→HF+H and OH+H2→H2O+H. The simplicity of these reactions makes them excellent models for uncovering the nature of chemical reactions. The high resolution time-of-flight Rydberg tagging method is used to detect the H atom produced from the reactions, providing us the most detailed information on angular distribution, velocity distribution and quantum-state distribution of the reactions.
