Definition of the Barn
The barn is a unit of area used in nuclear physics to measure the amount of surface that two particles may interact, for example, neutrons colliding with atomic nuclei.
- 1 barn is defined as
10⁻²⁸
square meters. - This is perhaps the reason for choosing the name 'barn' - a playful reference to the saying 'hit the broad side of a barn'; Indeed, relative to the questions addressed in nuclear physics, this cross-sectional area might appear to be rather broad.
The barn is much too small to be relevant in macroscopic measurements, such as land or real estate.
Barn Historical
The barn was first developed in the early 1940s in the Manhattan Project. Nuclear fission researchers seeking to design cross-sectional areas of nuclei engaged in nuclear reactions required convenient geometry to use.
The term barn was proposed by professors of physics M.G. Holloway and R. Harvey who strived to have this unit have a simple name easy to memorize. While it was rather funny that the concept of a barn arose from bomb-making, it didn't take long for it to be adopted in nuclear physics because it made practical sense.
Conversion to Other Units
Since the barn is used in nuclear physics, its conversions relate to extremely small areas. For comparison:
1
barn = 10⁻²⁸
square meters1
barn = 10⁻²⁴
square centimeters1
barn ≈ 1.076 × 10⁻²⁷
square feet1
barn ≈ 1.196 × 10⁻²⁷
square yardsThese values highlight the incredibly small scale of the barn compared to everyday units of area.
Uses of the Barn Today
The barn remains an essential unit in nuclear physics and particle physics, particularly in the study of:
- Fusion and Fission Research: Understanding the interaction of particles in nuclear reactors and fusion experiments.
- Nuclear Reactions: Describing the probability of interactions between particles like neutrons, protons, and nuclei.
- Particle Scattering: Quantifying the cross-sectional areas of particles in accelerators and reactors.
- Astrophysics: Used in studies involving cosmic particles and their interactions with matter.
Definition of Electron Cross Section
Mathematically, the cross section is expressed in units of area, typically in square meters (m²) or barns, where:
1
barn = 10^-28
m²Cross sections can vary depending on the energy of the incoming electron and the nature of the target particle.

Conversion to Other Units
While the electron cross section is not typically converted into macroscopic units like square feet or square yards, its standard conversions include:
1
barn = 10^-28
m²1
barn = 10^-24
cm²For reference, a square yard or square foot is astronomically larger than the typical electron cross section:
1
square yard = 0.836127
m²1
square foot = 0.092903
m²Thus, the electron cross section is a microscopic measurement suited only for quantum-scale phenomena.
Use in Measurement Today
The electron cross section remains a vital concept in physics and is used in the following contexts:
- Atomic and Molecular Physics: In order to quantify the probability of scattering, excitation, or ionisation of electrons in atomic and molecular collisions. Says Lawton: A cross section data is highly important for studying the reaction of chemicals and plasma.
- Nuclear Physics: Employed to investigate electron-nucleus interactions in helping realize forces as well as particle behavior.
- Radiation and Material Science: Contributes to understanding how electrons behave around other objects, essential for radiation detectors and exciting properties of materials.
- Astrophysics: Cross sections describe the physical processes of the interaction of cosmic particles and matters in space.
Comparison to Land Measurement Units
Electron cross section is very different from the units used in the measurement of land such as acres, square yards, or even square feet. On the one hand, there are macroscopic units of land measurement applied in practical life as in agriculture or property surveys, while the electron cross section is a truly quantum measure applied solely for scientific purposes only.
- Used to measure land area; equal to
43,560
square feet. - Used to measure interaction probabilities; typically in the range of
10^-28
m² or smaller.
