Solving Simultaneous Equations and Matrices
Equations (6) and (10) provide a solution to the simultaneous Equations (1) and (2). Introducing matrix notation for the simultaneous Equations (1) and (2) these solutions (6) and (10) form a pattern as follows. Define the matrix then . Then introduce two matrices formed from

Since core level electrons in solid-state atoms are quantized, the resulting energy spectra exhibit resonance peaks characteristic of the electronic structure for atoms at the sample surface.

The basic tool for measuring the number of electrons recorded for an atomic state is the quantification region. Figure 2 illustrates a survey spectrum where the surface is characterised using a quantification table based upon values computed from regions.
