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…

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…
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…
Further evidence for shape coexistence in Zn near doubly-magic Ni
L. Nies, L. Canete, D. D. Dao +31
Isomers close to doubly-magic Ni provide essential information on the shell evolution and shape coexistence near the and double shell closure.…
