Phys.) ; Neidherr, D (Mainz U., Inst.

Phys.) et al.
Collisions of ions with residual gas atoms in a Penning trap can have a strong influence on the trajectories of the ions, depending on the atom species and the gas pressure. We report on investigations of damping effects in time-of-flight ion-cyclotron resonance mass spectrometry with the Penning trap mass spectrometers ISOLTRAP at ISOLDE/CERN (Geneva, Switzerland) and SHIPTRAP at GSI (Darmstadt, Germany).

Phys. ; Darmstadt, GSI) ; Lunney, D (CSNSM, Orsay) et al.
High-accuracy mass measurements have been performed with the Penning trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The short-lived nuclides $^{70,71,72,73}$Se, $^{72,73,74,75}$Br, and $^{98,99,100,101,103}$Ag have been measured with an average uncertainty of a few keV. [...]

Restoration of the N=82 Shell Gap from Direct Mass Measurements of $^{132,134}$Sn
/ Dworschak, M (GSI, Darmstadt, Germany) ; Audi, G (CNRS, Univ. Paris Sud, Orsay, France) ; Blaum, K (GSI, Darmstadt, Germany ; Johannes Gutenberg-Univ., Mainz, Germany ; Max Planck Inst. for Nuclear Physics, Heidelberg, Germany) ; Delahaye, P (CERN) ; George, S (GSI, Darmstadt, Germany ; Johannes Gutenberg-Univ., Mainz, Germany) ; Hager, U (Univ. Jyväskylä, Jyväskylä, Finland) ; Herfurth, F (GSI, Darmstadt, Germany) ; Herlert, A (CERN) ; Kellerbauer, A G (Max Planck Inst. for Nuclear Physics, Heidelberg, Germany) ; Kluge, H J (GSI, Darmstadt, Germany ; Ruprecht-Karls-Univ., Heidelberg, Germany) et al.
A high-precision direct Penning trap mass measurement has revealed a 0.5-MeV deviation of the binding energy of $^{134}$Sn from the currently accepted value. The corrected mass assignment of this neutron-rich nuclide restores the neutron-shell gap at N=82, previously considered to be a case of “shell quenching.” In fact, the new shell gap value for the short-lived $^{132}$Sn is larger than that of the doubly-magic $^{48}$Ca which is stable.

Towards a magnetic field stabilization at ISOLTRAP for high-accuracy mass measurements on exotic nuclides
/ Marie-Jeanne, M ; Alonso, J ; Blaum, K ; Djekic, S ; Dworschak, M ; Hager, U ; Herlert, A (CERN) ; Nagy, S ; Savreux, R ; Schweikhard, L et al.
The field stability of a mass spectrometer plays a crucial role in the accuracy of mass measurements. In the case of mass determination of short-lived nuclides with a Penning trap, major causes of fluctuations are temperature variations in the vicinity of the trap and pressure changes in the liquid helium cryostat of the superconducting magnet.

The magnetic-field stability of a mass spectrometer plays a crucial role in precision mass measurements. In the case of mass determination of short-lived nuclides with a Penning trap, major causes of instabilities are temperature fluctuations in the vicinity of the trap and pressure fluctuations in the liquid helium cryostat of the superconducting magnet.
