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…

Energies and lifetimes of the 9p and 10p excited states in atomic francium

P. Lassègues, A. Ajayakumar, M. Athanasakis-Kaklamanakis +29

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…

Constraining the trend of the shell gap towards Sn with the masses of Cd

D. Lange, D. Atanasov, M. Au +24

We present the first determination of the empirical shell gap at by precise mass measurements of the neutron-deficient cadmium isotopes Cd with the ISOL…

Extending the low- "border'' of the region of deformation with precision mass spectrometry of Kr

D. Lunney, V. Manea, M. Mougeot +17

The onset of collective nuclear behavior in the , , region is examined through high-precision mass measurements of Kr, performed with the ISOLTRAP mas…

Laser spectroscopy and CP-violation sensitivity of actinium monofluoride

M. Athanasakis-Kaklamanakis, M. Au, A. Kyuberis +39

The apparent invariance of the strong nuclear force under combined charge conjugation and parity (CP) remains an open question in modern physics. Precision experiments with heavy a…

Refining the nuclear mass surface with the mass of Sn

L. Nies, D. Atanasov, M. Athanasakis-Kaklamanakis +17

Mass measurements with the ISOLTRAP mass spectrometer at CERN-ISOLDE improve mass uncertainties of neutron-deficient tin isotopes towards doubly-magic Sn. The mass uncertai…
