We probe the $N=82$ nuclear shell closure by mass measurements of neutron-rich cadmium isotopes with the ISOLTRAP spectrometer at ISOLDE-CERN. The new mass of $^{132}$Cd offers the first value of the $N=82$, two-neutron shell gap below $Z=50$ and confirms the phenomenon of mutually enhanced magicity at $^{132}$Sn. [...]

/ Mougeot, M. (CSNSM, Orsay) ; Atanasov, D. (Heidelberg, Max Planck Inst.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Chrysalidis, K. (CERN) ; Day Goodacre, T. (CERN ; Manchester U.) ; Fedorov, D. (St. Petersburg, INP) ; Fedosseev, V. (CERN) ; George, S. (Heidelberg, Max Planck Inst.) ; Herfurth, F. (Darmstadt, GSI) ; Holt, J.D. (TRIUMF) et al.
The neutron-rich isotopes $^{58-63}$Cr were produced for the first time at the ISOLDE facility and their masses were measured with the ISOLTRAP spectrometer. The new values are up to 300 times more precise than those in the literature and indicate significantly different nuclear structure from the new mass-surface trend. [...]

Mass measurements of $^{49,50}$Sc, $^{70}$As, $^{73}$Br and $^{196}$Hg nuclides produced at CERN's radioactive-ion beam facility ISOLDE are presented. The measurements were performed at the ISOLTRAP mass spectrometer by use of the multi-reflection time-of-flight and the Penning-trap mass spectrometry techniques. [...]

The strength of the $N$ = 28 magic number in neutron-rich argon isotopes is examined through high-precision mass measurements of $^{46-48}$Ar, performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN. The new mass values are up to 90 times more precise than previous measurements. [...]

Precision Mass Measurements of 129-131Cd and Their Impact on Stellar Nucleosynthesis via the Rapid Neutron Capture Process

Masses adjacent to the classical waiting-point nuclide 130Cd have been measured by using the Penning- trap spectrometer ISOLTRAP at ISOLDE/CERN. We find a significant deviation of over 400 keV from earlier values evaluated by using nuclear beta-decay data. [...]

Mass measurements of $^{99-101}$In challenge ab initio nuclear theory of the nuclide $^{100}$Sn
/ Mougeot, M. (Heidelberg, Max Planck Inst. ; CERN) ; Atanasov, D. (CERN) ; Karthein, J. (Heidelberg, Max Planck Inst. ; CERN) ; Wolf, R.N. (Sydney U.) ; Ascher, P. (CENBG, Gradignan) ; Blaum, K.

$^{100}$Sn is of singular interest for nuclear structure. Its closed-shell proton and neutron configuration exhibit exceptional binding and $^{100}$Sn is the heaviest nucleus comprising protons and neutrons in equal number, a feature that enhances the contribution of the short-range, proton-neutron pairing interaction and strongly influences its decay via the weak interaction.
