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. [...]

Precision Mass Measurements of 129-131Cd and Their Impact on Stellar Nucleosynthesis via the Rapid Neutron Capture Process
/ Atanasov, D. (Heidelberg, Max Planck Inst.) ; Ascher, P. (Heidelberg, Max Planck Inst.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Cakirli, R.B. (Istanbul U.) ; Cocolios, T.E. (Manchester U.) ; George, S. (Heidelberg, Max Planck Inst.) ; Herfurth, F. (Darmstadt, GSI) ; Kisler, D. (Heidelberg, Max Planck Inst.) ; Janka, H.T. ; Just, O. et al.
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. [...]

Precision Mass Measurement of $^{58-63}$Cr: Nuclear Collectivity towards the $N=40$ Island of Inversion
/ 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. [...]

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. [...]

$Q_{\textrm{EC}}$-value determination for $^{21}$Na$\rightarrow^{21}$Ne and $^{23}$Mg$\rightarrow^{23}$Na mirror-nuclei decays using high-precision mass spectrometry with ISOLTRAP at ISOLDE/CERN

We report on high-precision $Q_{\textrm{EC}}$ values of the $^{21}$Na$\rightarrow^{21}$Ne and $^{23}$Mg$\rightarrow^{23}$Na mirror $\beta$-transitions from mass measurements with ISOLTRAP at ISOLDE/CERN. A precision of $\delta m/m = 9 \cdot 10^{-10}$ and $\delta m/m = 1.5 \cdot 10^{-9}$ was reached for the masses of $^{21}$Na and $^{23}$Mg, respectively. [...]

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. [...]
