    In this problem, the students have to use the data presented in a spectroscopic analysis produced using the X-ray induced photoelectron spectrometry technique (XPS for X-Ray photoelectron spectroscopy) to authenticate an artwork. To conduct the analysis, the students need to understand various concepts related to the photoelectric effect that this spectroscopic technique is based on.
