Evidence of Two-Source King Plot Nonlinearity in Spectroscopic Search for New Boson
Joonseok Hur, Diana P. L. Aude Craik, Ian Counts +12
Optical precision spectroscopy of isotope shifts can be used to test for new forces beyond the Standard Model, and to determine basic properties of atomic nuclei. We measure isotop…

Evidence for Nonlinear Isotope Shift in Yb Search for New Boson
Ian Counts, Joonseok Hur, Diana P. L. Aude Craik +7
We measure isotope shifts for five Yb isotopes with zero nuclear spin on two narrow optical quadrupole transitions , ${}^2S_{1/2} \rightarr…
