Stark, n.3 Physics.|stɑːk|
The name of Johannes Stark (1874–1957), German physicist, used attrib. with reference to an effect observed by him (Sitzungsber. der k. Preuss. Akad. der Wissensch. (1913) 20 Nov. 932) in which spectral lines of a gas are broadened, split, or shifted when the source is in an electrostatic field (either applied externally or due to charged particles within it). Cf. Zeeman.
1914Science 2 Oct. 493/2 The Stark-electric effect differs from the Zeeman effect in that the various lines of the same series are not equally affected. 1939Nature 20 May 834/1 The spectroscopy team is drawn from an even wider area,..dealing..with atomic spectra, hyper⁓fine structure, Stark effect and related phenomena. 1962G. M. Barrow Introd. Molecular Spectrosc. v. 92 Some dipole-moment determinations that have been made using the Stark effect in rotational spectra. 1979Physical Rev. A. XX. 504/2 Stark-broadening parameters for the brighter isolated tin lines are given in Table VI. |
