Nuclear polarisation and relativistic effects contributions to King plot non-linearity

P. Munro-Laylim, V. A. Dzuba, V. V. Flambaum

The effect of nuclear polarisation on the non-linearities of King plot for isotope shift in Ca${}^{+}$, Sr${}^{+}$ and Yb${}^{+}$ ions is studied. These ions are currently used in search for t…
