Probing the electroweak structure of nuclei with rare atoms and molecules
Silviu-Marian Udrescu, Antoine Belley, Jason D. Holt +2
Precision experiments of atoms and molecules have become a powerful probe of the electroweak structure of atomic nuclei and of physics beyond the Standard Model. We review how the…
Radioactive Molecules as Laboratories of Fundamental Physics
A. Jadbabaie, S. Ebadi, R. F. Garcia Ruiz +3
Radioactive molecules provide a powerful new platform in the search for new physics at energy scales complementary to high-energy particle colliders. By combining enhancements from…
Design and Performance of a Heated Gas Injector for Producing Cold Molecular Beams
Avneesh Verma, Jack Mango, Shungo Fukaya +4
We realize an injector device that supplies warm gas directly into a cryogenic environment. This injector has several advantageous features, including robustness, rigidity, simple…
Non-destructive cavity readout of molecules for precision measurements
Alejandro Salas-Estrada, Silviu-Marian Udrescu, Geoffrey Zheng +6
We propose a non-destructive method to measure the population of molecules in a selected rotational-hyperfine state by coupling them to a high-finesse optical cavity. In contrast t…
Energies and lifetimes of the 9p and 10p excited states in atomic francium
Pierre Lassègues, P. Lassègues, A. Ajayakumar +35
We present the first measurement of 9p 2P1/2,3/2 and 10p 2P1/2,3/2 excited levels absolute wavenumbers and radiative lifetime in francium. We used the Collinear Resonance Ionizatio…

The ionization potential (IP) of radium monofluoride (RaF) was measured to be 4.969(2)[10] eV, revealing a relativistic enhancement in the series of alkaline earth monofluorides. T…
Parity and time-reversal symmetry violation in diatomic molecules: LaO, LaS and LuO
Yuly Chamorro, Victor Flambaum, Ronald F. Garcia Ruiz +2
The violation of parity (P) and time-reversal (T) symmetry is enhanced in the LaS, LaO and LuO molecules due to the existence of states of opposite parity with small energy differe…
Isotope-shift factors with quantum electrodynamics effects for many-electron systems: A study of the nuclear charge radius of Al
Leonid V. Skripnikov, Sergey D. Prosnyak, Aleksei V. Malyshev +7
A method for calculating the field shift contribution to isotope shifts in many-electron atoms, incorporating quantum electrodynamics (QED) effects, is introduced. We also implemen…
Radiative lifetime of the A 2Π1/2 state in RaF with relevance to laser cooling
