One potential dark matter candidate is a light boson coupling neutrons and electrons. Such a hypothetical fifth force could be detected through so-called King plots, where the isotope shifts of two optical transitions are plotted against each other for a series of isotopes. Deviations from the expected linearity could reveal such a fifth force. To extract non-linearity effects by higher-order SM, the generalized King plot can be used, which requires an extended number of transitions and isotopes. For this, we investigate in calcium and xenon forbidden transitions in highly charged states. We analyze theoretically their King plot sensitivity to a hypothetical fifth-force, for future high-precision coherent laser spectroscopy measurements.
