Search for the 229Pa Parity Doublet via Internal-Conversion Spectroscopy at FRIB
Silviu-Marian Udrescu, Aiden Boyer, Lan Cheng +7
The radioisotope Pa is predicted to possess a nearly degenerate ground-state parity doublet. Previous -ray and conversion-electron spectroscopy suggests a splitting of $…
Precise and accurate nuclear electric quadrupole moment of Ra from molecular spectroscopy
C. M. Fajardo-Zambrano, M. Athanasakis-Kaklamanakis, L. Lalanne +30
Nuclear electric quadrupole moments of unstable isotopes are commonly extracted from laser spectroscopy of the atomic hyperfine structure, where the accuracy is limited to the seve…
CREMA: Collinear Resonance for Exotic Molecules and Atoms
Fabian C. Pastrana Cruz, Shane G. Wilkins, Alex J. Brinson +19
The Collinear Resonance for Exotic Molecules and Atoms (CREMA) setup has been developed and commissioned at the Massachusetts Institute of Technology's Laboratory for Nuclear Scien…
A Differentiable Surrogate for Loss-Dominated Ion Beam Transport
Jose M. Munoz-Arias, Laura Ruiz-Arango, Derick Gonzalez-Acevedo +3
Radioactive nuclei with extreme proton-to-neutron ratios provide unique probes of nuclear structure, fundamental symmetries, astrophysical processes, and applications such as medic…
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…
Laser spectroscopy illuminates the shell closure
Tim E. Lellinger, Liss V. Rodriguez, Patrick Muller +29
Atomic nuclei are strongly correlated quantum many-body systems, and how their shell structure evolves with increasing neutron excess remains a central open question in nuclear phy…
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…
Ab initio calculation of symmetry-breaking observables
A Belley, B. Romeo, J. Engel +8
Symmetry-violating observables such as the nuclear anapole and Schiff moments provide sensitive probes of the fundamental symmetries of nature and physics beyond the Standard Model…
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…
Towards Collinear Laser Spectroscopy of Radioactive Molecules Utilizing In-trap Produced Molecular Ion Beam
W. C. Mei, S. J. Chen, X. F. Yang +14
Molecules containing short-lived isotopes, namely radioactive molecules, are among the most promising candidates for probing new physics beyond the Standard Model, although their p…
Linking Electromagnetic Moments to Nuclear Interactions with a Global Physics-Driven Machine-Learning Emulator
Jose M. Munoz, Antoine Belley, Andreas Ekström +3
Understanding how specific components of the nuclear interaction shape observable properties of atomic nuclei remains a central challenge in nuclear structure research. While previ…
