Abstract

A potassium rf electrodeless discharge is described which, when placed in a kilogauss magnetic field, emits intense and well resolved Zeeman components of the resonance lines at 7665 Å and 7699 Å. The lamp is particularly suitable for studies of atomic fluorescence using Zeeman scanning techniques.
