Reaction dynamics of transition metal atoms

Transition metal atoms(TM) play important roles in various catalytic reactions. In this research project, the collisions and reactions of the TM atoms with molecules were studied experimentally to clarify the mechanism of the catalytic abilities of TM. One characteristics of the TM atoms is the electronic structure. It can be easily mediated by the presence of other molecules, reactants. Here, a crossed-beam technique was used to study the collision of TM with O_2 under single collision condition and velocity/angular distributions of products were determined. These information were useful to clarify the interaction between TM and O_2 and the presence of intermediates.
