Raman Transitions in Collinear Laser Spectroscopy for High-Precision Frequency Measurements

Julien Spahn, Hendrik Bodnar, Kristian König +2

We demonstrate stimulated Raman spectroscopy on dipole-forbidden fine-structure transitions in a fast ion beam. It is applied to the S1/2​→D5/2​ c…

Accurate Charge Radius Measurement of 14C Confronts Ab Initio Theory

Kristian König, Patrick Müller, Tobias Gesser +11

Located at the neutron shell closure N=8, the long-lived radioactive isotope 14C plays a critical role in geochronology and nuclear structure studies. Despite its widespre…

Laser spectroscopy illuminates the N=32 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…

The N=126 Factory: A New Multi-Nucleon Transfer Reaction Facility

A. A. Valverde, M. S. Martin, W. S. Porter +23

Multi-nucleon transfer (MNT) reactions between two heavy ions offer an effective method of producing heavy, neutron-rich nuclei that cannot currently be accessed efficiently using…
