X-Rays on the Surface

• The X-Rays will penetrate to the core e^- of the atoms in the sample.

• Some e^-s are going to be released without any problem giving the Kinetic Energies (KE) characteristic of their elements.

• Other e-s will come from inner layers and collide with other e-s of upper layers

• These e^- will be lower in lower energy.

• They will contribute to the noise signal of the spectrum.
