Penning traps are excellent high-precision mass spectrometers for radionuclides. The high-resolving power used for cleaning isobaric and even isomeric contaminants can be exploited to improve decay-spectroscopy studies by delivering purified samples. [...]

MATS and LaSpec: High-precision experiments using ion traps and lasers at FAIR
/ Rodriguez, D (Granada U.) ; Kowalska, M (Heidelberg, Max Planck Inst.) ; Scheidenberger, C (Darmstadt, GSI ; Giessen U.) ; Kreim, S (Heidelberg, Max Planck Inst.) ; Gomez-Hornillos, M B (Barcelona, Polytechnic U.) ; Aysto, J (Jyvaskyla U.) ; Dickel, T (Giessen U.) ; Geppert, C (Mainz U.) ; Novikov, Y N (St. Petersburg, INP ; St. Petersburg State U.) ; Tain, J L (Valencia U., IFIC) et al.
Nuclear ground state properties including mass, charge radii, spins and moments can be determined by applying atomic physics techniques such as Penning-trap based mass spectrometry and laser spectroscopy. The MATS and LaSpec setups at the low-energy beamline at FAIR will allow us to extend the knowledge of these properties further into the region far from stability. [...]

High-precision mass measurements of neutron-deficient Tl (A=184, 186, 190, 193–195, 198) isotopes as well as Pb (A=202,208), Fr (A=207,208), and Ra (A=224) are performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The improved precision of the mass data now allows the study of subtle odd-even effects. [...]

High-precision mass measurements of stable and beta-decaying nuclides $^{52-57}$Cr, $^{55}$Mn, $^{56,59}$Fe, $^{59}$Co, $^{75, 77-79}$Ga, and the lanthanide nuclides $^{140}$Ce, $^{140}$Nd, $^{160}$Yb, $^{168}$Lu, $^{178}$Yb have been performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The new data are entered into the Atomic Mass Evaluation and improve the accuracy of masses along the valley of stability, strengthening the so-called backbone. [...]

Probing the N = 32 shell closure below the magic proton number Z = 20: Mass measurements of the exotic isotopes $^{52,53}$K
/ Rosenbusch, M. (Greifswald U.) ; Ascher, P. (Heidelberg, Max Planck Inst.) ; Atanasov, D. (Heidelberg, Max Planck Inst.) ; Barbieri, C. (Surrey U.) ; Beck, D. (Darmstadt, GSI) ; Blaum, K.

(Heidelberg, Max Planck Inst. ; Istanbul U.) ; Cipollone, A. (Surrey U.) et al.
The recently confirmed neutron-shell closure at N = 32 has been investigated for the first time below the magic proton number Z = 20 with mass measurements of the exotic isotopes 52,53K, the latter being the shortest-lived nuclide investigated at the online mass spectrometer ISOLTRAP. The resulting two-neutron separation energies reveal a 3 MeV shell gap at N = 32, slightly lower than for 52Ca, highlighting the doubly-magic nature of this nuclide. [...]

An extension of the atomic mass surface in the region A≈100 was performed via measurements of the $^{100−102}$Sr and $^{100−102}$Rb masses with the ion-trap spectrometer ISOLTRAP at CERN-ISOLDE, including the first direct mass determination of $^{100−102}$Sr and $^{100−102}$Rb. These measurements confirm the continuation of the region of deformation with the increase of neutron number, at least as far as $N=65$. [...]
