differential spectrum

https://doi.org/10.1351/goldbook.09319

Differential of a direct spectrum with respect to energy by an analogue electrode modulation method or by the numerical differentiation of that spectrum.

Notes:
  1. Used in Auger electron spectroscopy and, rarely, in X-ray photoelectron spectroscopy.
  2. The modulation amplitude (for example in unit eV) or the number of points and the type of differentiating function should be given.
