Nonlinear calcium King plot constrains new bosons and nuclear properties

A. Wilzewski, L. I. Huber, M. Door +39

Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…

Unexpectedly large difference of the electron density at the nucleus in the 4p $^{2}$ P $_{1/2, 3/2}$ fine-structure doublet of Ca $^{+}$

C. Shi, F. Gebert, C. Gorges +9

We measured the isotope shift in the $^{2}$ S $_{1/2}$ - $^{2}$ P $_{3/2}$ (D2) transition in singly-ionized calcium ions using photon recoil spectroscopy. The high accuracy of the technique…
