Square Millimeter [mm²]

A square millimeter (mm²) is a unit of area equal to a square with sides 1 millimeter long. It is used to measure very small surfaces, such as parts of mechanical components or electronic circuits.

1 mm² = 0.000001 m².

Electron Cross Section

The electron cross section is a measure of the probability that an electron will interact with a target particle (like an atom or nucleus) during scattering or collision processes. It represents an effective area that quantifies the likelihood of interaction.

  Typically measured in units called barns (1 barn = 10⁻²⁸ m²) or square meters.

  
  
• 
  

  Used in fields like nuclear physics, atomic physics, and materials science.

  
  
• 
  

  Cross sections vary depending on the energy of the electron and the nature of the target.

  
  

It helps scientists understand and predict how electrons scatter, absorb, or cause reactions at the microscopic level.
