The magnetic splitting of spectral lines. A scanning Fabry-Perot interferometer is used to measure the Zeeman effect in mercury and neon. The results are compared with the expectations derived from the vector model for the addition of atomic and nuclear angular momenta. A value of the ratio e/m of the electron is derived from the data.
