The Zeeman Effect of Krypton

Abstract

Measurements on the Zeeman effect about 130 lines in the spectrum of neutral krypton have yielded a large number of additional $g$ values to those already given by Pogany. In several cases, our results differ sharply from Pogany's, especially in the case of $4p^{5}5s$. The $g$ sum rule has been verified for $4p^{5}5s$, $4p^{5}5p$ and for $J=2\mathrm{} \mathrm{of} 4p^{5}6p$, but for this last configuration, interaction with $4p^{5}5f$ causes the breakdown of the rule for $J=1\mathrm{}$. Other anomalies in the $g$ values are also discussed.
