Non-Periodic Systems (Amorphography),ontrast to the quasicrystalline materials discussed in the next Chapter which, although nonperiodic and lacking extended symmetry, still retain long range order and hence give rise to sharp Bragg-like peaks in their diffraction pattern. This Chapter will describe the general principles involved in s

Measurement of the Energy Gap in High Tc Superconductors by Electron Spectroscopies,ng measurements. The purpose of this paper is to show that high resolution photoemission and energy loss spectrocopies can give very important informations on the value of the gap, its anisotropy, its temperature dependence and the symmetry of the superconducting order parameter.
