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.
