Energy and Chemical Change

Abstract

A cluster heated and compressed by an impact at a surface has been studied as a medium for driving chemistry under controlled extreme conditions. The following aspects were examined: Is the temperature rise following impact sufficient to overcome high barriers to reactions; what is the range of impact velocities that is useful for this purpose; does the cluster retain enough of its integrity for a length of time sufficient that chemistry can take place within it; what is the role of electronically non-adiabatic processes; what is the mechanism of activation within the hot and compressed cluster; what is the mechanism for ionization in the hot cluster and in other very energy rich systems; can specific examples of cluster impact induced chemistry be provided. Detailed discussions of these questions are provided in published papers and in two reviews.
