Query: Multidimensional King-plot analysis for accurate extraction of Cd
  nuclear charge radii: a challenge for nuclear structure theory   High-accuracy determination of isotope shift factors, which plays a crucial
role in accurate extraction of nuclear charge radius, is well-known to be
challenging experimentally and theoretically. Nonetheless, based on an accurate
measurement of the isotope shifts for the Cd$^+$ $5s~^2S_{1/2}-5p~^2P_{3/2}$
and the Cd $5s^2~^1S_0-5s5p~^1P_1$ transition, a multidimensional King-plot
analysis is performed to extract the atomic field shift and mass shift factors
accurately. The results are further cross-checked against results from atomic
structure calculations using a high-accuracy configuration interaction and
many-body perturbation theory. Combined with previous isotope shifts, nuclear
charge radii for $^{100-130}$Cd of the highest accuracy are reported. For the
neutron-rich region, accuracies for the charge radii are improved by nearly one
order of magnitude. This work provides a coherent and systematic extraction of
Cd nuclear charge radii from isotope shifts. The results offer stringent
testing and possible challenges to the latest advances in nuclear theory and
excellent benchmarking to the atomic structure calculations.
