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…

Radiative lifetime of the A 2Π1/2 state in RaF with relevance to laser cooling

M. Athanasakis-Kaklamanakis, S. G. Wilkins, P. Lassègues +38

The radiative lifetime of the (v=0) state in radium monofluoride (RaF) is measured to be 35(1) ns. The lifetime of this state and the related decay rate $Γ= 2.86(8…

Nuclear matter radii from molecular rotations using ultra-high-resolution spectroscopy

Michail Athanasakis-Kaklamanakis, Gerda Neyens

The rotational constant parametrizes the relative spacing between a molecule's rotational energy levels. It depends on the molecule's classical moments of inertia, which, in all st…

Electromagnetic Properties of Indium Isotopes Elucidate the Doubly Magic Character of Sn

J. Karthein, C. M. Ricketts, R. F. Garcia Ruiz +24

Our understanding of nuclear properties in the vicinity of Sn, suggested to be the heaviest doubly magic nucleus with equal numbers of protons (Z=50) and neutrons (N=50), h…

Pinning down electron correlations in RaF via spectroscopy of excited states and high-accuracy relativistic quantum chemistry

M. Athanasakis-Kaklamanakis, S. G. Wilkins, L. V. Skripnikov +53

We report the spectroscopy of the 14 lowest excited electronic states in the radioactive molecule radium monofluoride (RaF). The observed excitation energies are compared with full…

Ab initio study of electronic states and radiative properties of the AcF molecule

Leonid V. Skripnikov, Alexander V. Oleynichenko, Andréi Zaitsevskii +4

Relativistic coupled-cluster calculations of the ionization potential, dissociation energy, and excited electronic states under 35,000 cm are presented for the actinium mono…
