Zusammenfassung
The use of a variable voltage method to improve the absorption
correction for soft x-ray analysis has been studied. It is shown that
the sample composition and the absorption correction can be deduced
simultaneously, and that matrix-dependent changes to mass absorption
coefficients are automatically taken into account. No more than three
accelerating voltages need be used, and the method is insensitive to
small errors in the shape of phi(rhoz).
