(01 Jan 1995)

<physics> Refers to the close approach of two or more particles, photons, atoms, nuclei, etc, during which such quantities as energy, momentum, and charge may be altered.

More-or-less synonymous with scattering, except in scattering one generally thinks of one of the particles as being at rest, and the other colliding particles scatter from their initial direction of motion due to the collision.
