High-resolution isotope-shift spectroscopy of Cd i

We present absolute frequency measurements of the ${}^{1}\text{P}_1 \leftarrow {}^{1}\text{S}_0$ ($229$nm) and ${}^{3}\text{P}_1 ($326$nm) transitions for all naturally occurring isotopes cadmium. The isotope shifts hyperfine intervals fermionic are determined with an accuracy 3.3MHz. find that quantum interference in laser-induced fluorescence spectra transition causes error up to 29(5)MHz determining splitting, when not accounted appropriate model. Using a King-plot analysis, we extract field- mass-shift parameters determine nuclear charge radius differences fermions. lifetime $^1\text{P}_1$ state is be 1.60(5)ns by measuring natural linewidth transition. These results resolve significant discrepancies among previous measurements.
