9. There are alloy systems with greater 'ionicity' which may be expected to exhibit more dramatic disorder effects. However this tendency favours the formation of intermetallics rather than solid solutions, i.e. disordered phases may not exist. The CuPd alloy system forms substitutionally disordered alloys at all compositions and is therefore a good test case for the study of electrostatics in disordered alloys. Furthermore, Cu 2p levels excited by Al K α radiation give rise to photoelectron lines which are both narrow and dominated by bulk emission.

11. In general the linear dependence of V̄ on c may not be strictly reproduced by experimental core XPS shifts due changes in surface dipole, relaxation energy and valence configuration.
