“…A recently introduced operation mode featuring crossed laser/atom beam geometry (Heinke et al, 2017;Heinke, 2019) additionally offers a way to enhance spectral resolution approaching the capabilities of collinear spectroscopy setups. This technique was employed off-line already for various nuclear structure studies of long-lived radioactive atomic species (Heinke, 2019;Studer et al, 2020;Kron et al, 2020).…”

Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei. In this manuscript, we review the scientific case for studying radioactive molecules, discuss recent atomic, molecular, nuclear, astrophysical, and chemical advances which provide the foundation for their study, describe the facilities where these species are and will be produced, and provide an outlook for the future of this nascent field.

“…Advents in modern computing allow for relativistic atomic structure calculations to be performed with results consistent with experimentally determined values to a few parts in 10 5 [21][22][23][24]. Such computations are also used to determine mass and field shift parameters of isotope shifts for King plot analyses [4,10,[25][26][27][28][29]. Low-lying energy levels in ytterbium have been explored through computational means [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], however they do not compute isotopes separately and often avoid the 3 P o 0 state.…”

Relativistic multiconfiguration Dirac-Hartree-Fock calculations with configuration interaction are carried out for the 1 S0 and 3 P o 0,1 states in neutral ytterbium by use of the available grasp2018 package. From the resultant atomic state functions and the ris4 extension, we evaluate the mass and field shift parameters for the 1 S0 − 3 P0 (clock) and 1 S0 − 3 P o 1 (intercombination) lines. We present improved estimates of the nuclear charge parameters, λ A,A , and differences in mean-square charge radii, δ r 2 A,A , and examine the second-order hyperfine interaction for the 3 P o 0,1 states. Isotope shifts for the clock transition have been estimated by three independent means from which we predict the unknown clock line frequencies in bosonic Yb isotopes. Knowledge of these line frequencies has implications for King plot nonlinearity tests and the search for beyond Standard-Model signatures.
