An analysis is presented of issues involved in peak location for the calibration of the binding energy (BE) scales of x-ray photoelectron spectrometers. These issues include the e †ects of peak asymmetry, the surface core-level shift, and the avoidance of a sloping background when Ðtting spectra for

✦ Synopsis
The algorithms proposed for determination of the position in XPS are analysed. The method of bisected chords is reformulated in a form readily available for digital-computers, another derivation of fitting a parabola to the top of peak is given and some more non-iterative methods are presented. The suggested methods determine different characteristics of the photopeak, such as 'peak location', maximum height, centre of gravity and the distribution parameter.

Knowledge of the location of saddle points is crucial to the study the chemical reactivity. Using a path following method defined in a reduced potential energy surface, and starting at either the reactant or product region, we propose an algorithm that locates the corresponding saddle point. The red
