Electron Escape from Solid Targets,ninduced-electron spectroscopy. The discussion here is restricted to the case of noncrystalline solids since structural effects are not important for the physical processes under consideration. Electron escape from a crystal lattice is discussed in Chap. 7.

Binary-Encounter Electron Emission from Crystals,dence conditions. The theoretical models used for understanding the phenomena are, in part, an extension of those introduced for the analysis of monoenergetic electron emission in Chap. 7. Note that the experimental electron spectra presented here are raw data, i.e. the electron yield is the number

Related Topics,gy electron emission from crystal surfaces. The production and escape processes of low-energy electrons have been discussed extensively in a number of review articles cited in Chap.1, and are beyond the scope of this monograph. The following discussion is therefore focused only on the kind of knowle

Concluding Remarks,at are produced by the binary-encounter processes in solids bombarded by fast ions. The binary-encounter electron yield considered here results from multiple scattering of energetic ions and electrons, which would require numerical calculations in an . approach. It has been demonstrated, however, th

Normally an algorithm is applicable only to a narrowly limited group of problems. Such is for instance the Euclidean algorithm, which determines the greatest common divisor of two numbers, or the well-known procedure which is used to obtain the square root of a natural number in decimal notation.
