Abstract

When nonmetallic materials fracture a number of particles are emitted including ions, electrons, metastables, neutrals and photons. These particles may be ejected from the material for times ranging from microseconds to several minutes after the fracture occurred. Attempts to correlate the onset of emission with the time of crack formation have led to some interesting observations regarding the correlations, in time, of the release of electrons and ions in this process. We find that some electrons and ions are released in coincidence with a time resolution of 250 ns. An electron stimulated desorption model is proposed to explain the ion and excited neutral emission accompanying fracture.
