rutherford scattering
SpecializedAcademic / Technical
Definition
Meaning
A physical phenomenon where charged particles (typically alpha particles) are deflected by the electric field of an atomic nucleus.
In modern physics, this term refers specifically to the scattering of particles by a Coulomb (electrostatic) potential, famously used by Ernest Rutherford to deduce the existence of a dense, positively charged atomic nucleus.
Linguistics
Semantic Notes
Almost exclusively used in physics contexts, particularly nuclear, particle, and atomic physics. The term is inherently tied to Rutherford's 1911 experiment and its implications.

Not used.
Academic
Primary usage. Found in physics lectures, textbooks, and research papers on atomic/nuclear structure, materials analysis (RBS).
Everyday
Extremely rare. Would only occur in popular science discussions of atomic history.
Technical
Precise term in experimental and theoretical physics. Refers to a specific scattering process with a well-defined cross-section.
Examples
By Part of Speech

Examples
By CEFR Level
- Rutherford scattering was a very important experiment in science.

Conceptual Metaphor
PROBING STRUCTURE IS SCATTERING (The experimental method (scattering) is the primary vehicle for understanding the hidden, fundamental structure of matter).

Common Pitfalls
Translation Traps (for Russian speakers)
- "Рассеяние Резерфорда" is the direct, correct translation. Avoid literal translations like "разбрызгивание Резерфорда".
Common Mistakes
- Misspelling as 'Rutherfod scattering' or 'Rutherfurd scattering'.
- Confusing it with Thomson scattering (scattering by electrons).
- Using it as a general term for any particle scattering, rather than specifically Coulomb/nuclear scattering.

Frequently Asked Questions
Rutherford scattering is the deflection of charged particles by a heavy atomic nucleus (Coulomb scattering). Thomson scattering is the deflection of electromagnetic radiation (like light) by free or loosely bound electrons.
Yes. The principle is the basis for Rutherford Backscattering Spectrometry (RBS), a common materials analysis technique used to determine the composition and structure of thin films.
Gold can be hammered into an extremely thin foil (only a few atoms thick), minimizing the chance of multiple scatterings and allowing clear observation of single, large-angle deflections.
While most alpha particles passed straight through the foil, a very small fraction were deflected at very large angles, including directly backwards. This was inconsistent with the prevailing 'plum pudding' atomic model and implied a tiny, massive, positively charged core.
