Periodic Table of Principal XPS BEs

Periodic Table of XPS BEs from Principal XPS Signals
were NOT measured by NIST

These XPS BES are the mean values of BEs measured, not by NIST,
but by Crist, Ulvac-PHI, Martensson, and JEOL.

NOTE:  NIST has NEVER MEASURED any XPS binding energies
from any pure materials, pure elements, or pure metals.
