 XPS  IMFP Grapher

 Inelastic mean free paths calculation.

This program uses the modeling functions of the IMFP from two publications:

Elastic Scateering corrections in AES and XPS. II
Estimating Attenuation Lengths and Conditions Required for their Valid Use in Overlayer/Substrate Experiments
P.J.Cumpson and M.P. Seah

Quantitative Electron Spectroscopy of Surfaces:
A standard Data Base for Electron Inelastic Mean Free Paths in Solids.
M.P.Seah and W.A. Dench


You can also use the help of a database to calculate a matrix density.
