Comprehensive Inclusion of Higher-order Ca $^{+}$ Isotope Shifts in the King's Plot Yields an Order Improvement on the $e^{-}$ - $n$ Coupling Limit

Vaibhav Katyal, A. Chakraborty, B. K. Sahoo

By critically evaluating higher-order nonlinear effects to the isotope shifts (ISs) in the low-lying transition frequencies of the singly charged calcium ion, stringent constraint…

Testing for isospin symmetry breaking with extensive calculations of isotope shift factors in potassium

Vaibhav Katyal, A. Chakraborty, B. K. Sahoo +4

Precise evaluation of the isotope shift (IS) factors for seven low-lying potassium (K) states is achieved using relativistic coupled-cluster (RCC) theory. The energies of these sta…
