Hyperfine-Structure Measurements of ExcitedSStates of the Stable Isotopes of Potassium, Rubidium, and Cesium by Cascade Radio-Frequency Spectroscopy

Abstract

The hyperfine structure of several of the excited $S$ states of the stable isotopes of potassium, rubidium, and cesium has been measured by the method of cascade radio-frequency spectroscopy. We find, for the magnetic dipole coupling constant $A$, in MHz, for ${\mathrm{K}}^{39}$: $A\left(5\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=55.50\mathrm{}\left(60\right)\mathrm{}$, $A\left(6\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=21.81\mathrm{}\left(18\right)\mathrm{}$; for ${\mathrm{K}}^{41}$: $A\left(5\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=30.75\mathrm{}\left(75\right)\mathrm{}$, $A\left(6\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=12.03\mathrm{}\left(40\right)\mathrm{}$; for ${\mathrm{Rb}}^{85}$: $A\left(6\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=239.3\mathrm{}\left(1.2\right)\mathrm{}$, $A\left(7\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=94.00\mathrm{}\left(64\right)\mathrm{}$, $A\left(8\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=45.5\mathrm{}\left(2.0\right)\mathrm{}$; for ${\mathrm{Rb}}^{87}$: $A\left(6\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=809.1\mathrm{}\left(5.0\right)\mathrm{}$, $A\left(7\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=318.1\mathrm{}\left(3.2\right)\mathrm{}$, $A\left(8\mathrm{}{}_{}{}^2{}_{}{}^{}S_{\frac{1}{2}}^{}{}_{}{}^{}\right)=158.0\mathrm{}\left(3.0\right)\mathrm{}$; for
