Isotope shift and hyperfine splitting of the $4s \rightarrow 5p$ transition in potassium (1103.2908v1)
Published 15 Mar 2011 in physics.atom-ph and cond-mat.quant-gas
Abstract: We have investigated $4s\;2S_{1/2} \rightarrow 5p\;2P_{1/2}$ transition ($D_1$ line) of the potassium isotopes ${39}$K, ${40}$K, and ${41}$K using Doppler-free laser saturation spectroscopy. Our measurements reveal the hyperfine splitting of the $5p\;2P_{1/2}$ state of ${40}$K and we have determined the specific mass shift and the nuclear field shift constants for the blue $D_1$ line.
