Measuring and modeling absolute data for electron-induced processes

This article draws a connecting line between a number of publications scattered in the literature with the aim of making some general conclusions. Emphasis is on dissociative electron attachment (DAE), since this process leads to chemical change, essential for many applications. Four domains of phenomena involved in DEA are identified: threshold or 'nonlocal' phenomena, the 'multidimensional' phenomena, the Feshbach resonance domain, and processes where scrambling of atoms occurs. The point is made that these four groups of phenomena are linked in real world, and that a unified theory describing all of them is required.
