WebThe Mean Free Path (MFP) of an electron is the average distance an electron travels within a specimen between events of a specific type (e.g., elastic scattering or ionization). The probability (Q) that an electron with 20 keV of energy will cause an Fe Kα ionization is 3.96 x 102 (barns/atom; 1 barn = 1 x 10-10 nm2 ). http://hyperphysics.phy-astr.gsu.edu/hbase/Kinetic/menfre.html

In physics, mean free path is the average distance over which a moving particle (such as an atom, a molecule, or a photon) travels before substantially changing its direction or energy (or, in a specific context, other properties), typically as a result of one or more successive collisions with other particles. See more Imagine a beam of particles being shot through a target, and consider an infinitesimally thin slab of the target (see the figure). The atoms (or particles) that might stop a beam particle are shown in red. The magnitude … See more In the kinetic theory of gases, the mean free path of a particle, such as a molecule, is the average distance the particle travels between collisions with other moving particles. The derivation above assumed the target particles to be at rest; therefore, in reality, the formula See more • Scattering theory • Ballistic conduction • Vacuum • Knudsen number See more Radiography In gamma-ray radiography the mean free path of a pencil beam of mono-energetic photons is the average distance a photon travels between collisions with atoms of the target material.
