The Zeeman Effect in the Spectrum of Neon

Abstract

Measurements on about two hundred and fifty lines of the spectrum of neon in fields of 27,000-32,000 gauss have now been completed. The neon discharge was excited by means of an electrodeless high frequency discharge (about 40 megacycles) at right angles to the magnetic field and to the line of sight. The lines, extending from about $\lambda \lambda 3100-9000\mathrm{A}$ include transitions involving all of the levels of the $2p^{5}4p$, the $2p^{5}3d$, $2p^{5}4d$ configurations, and parts of others. A large number of "forbidden" lines also appear.
