self-repulsionn.

Brit.

/ˌsɛlfrᵻˈpʌlʃn/, U.S.

/ˌsɛlfrəˈpəlʃ(ə)n/

Origin: Formed within English, by derivation. Etymons: self- prefix, repulsion n.

Etymology: < self- prefix + repulsion n., after self-repellent adj., self-repelling adj. Compare self-repulsive adj. and earlier self-repellency n.

With reference to particles, molecules, etc., of the same substance or type: the action or property of repelling each other, esp. by the electromagnetic force. In early use also with reference to a substance: the property of tending to expand due to consisting of particles which repel each other. Cf. self-repellency n.

1814 Philos. Mag. 44 338 The electric matter when issuing from a pointed body in open air, appears like a diverging cone of rays, which Dr. Franklin thinks must be caused by self repulsion.

1834 W. Prout Chem., Meteorol. & Function Digestion App. 555 The individual molecules of the gas..are thus enabled to assume that position..in which their mutual self-repulsion is the greatest possible.

1862 Notices Proc. Royal Inst. Great Brit. 3 424 Liquid diffusion may be attributed to a self-repulsion of the particles of the salt or other body which diffuses.

1929 Science 17 May 511/1 As the electrons advance towards the anode they spread apart owing to self-repulsion and diffusion.

1971 Sci. News 10 Apr. 249/3 All parts of the electron are charged, and each repels all the others since they all have negative charge. Something is necessary to counteract this self-repulsion.

2013 Proc. National Acad. Sci. U.S.A. 110 20085/1 The reduced self-repulsion of DNA makes it more prone to self-entangle.
