摘要: Hyperfine structure $A$ and $B$ factors of the atomic $5s\,5p\,\; ^3\rm{P}_2 \rightarrow 5s\,6s\,\; ^3\rm{S}_1$ transition are determined from collinear laser spectroscopy data $^{107-123}$Cd $^{111m-123m}$Cd. Nuclear magnetic moments electric quadrupole extracted using reference dipole calculated field gradients, respectively. The hyperfine anomaly for isotopes with $s_{1/2}$ $d_{5/2}$ nuclear ground states isomeric $h_{11/2}$ is evaluated a linear relationship observed all except $s_{1/2}$. This corresponds to Moskowitz-Lombardi rule that was established in mercury region chart but case cadmium slope distinctively smaller than mercury. In total four ionic levels were analyzed them exhibit similar behaviour. gradient ^3\mathrm{P}_2$ level derived multi-configuration Dirac-Hartree-Fock calculations order evaluate spectroscopic moments. results consistent those obtained an based on calculation.
