noun

The splitting of spectral lines that occurs when their source is in a magnetic field so strong that the splitting of each line is comparable in magnitude to the separation of adjacent lines in a multiplet.

The spacing of the lines corresponding to the normal Zeeman effect rather than the anomalous Zeeman effect generally observed at lower field strengths..

Origin

1920s; earliest use found in Henry Brose (b. 1890). From the names of Louis Carl Heinrich Friedrich Paschen and Ernst Emil Alexander Back, German physicist, who jointly published a description of the effect in 1913 (Ann. der Physik 39 897) + effect.
