Evolution of nuclear ground-state properties of neutron-deficient isotopes around Z=82 from precision mass measurements
/ Böhm, Ch (Heidelberg, Max Planck Inst.) ; Borgmann, Ch (Heidelberg, Max Planck Inst.) ; Audi, G (CSNSM, Orsay) ; Beck, D (Darmstadt, GSI) ; Blaum, K (Heidelberg, Max Planck Inst.) ; Breitenfeldt, M (Leuven U.) ; Cakirli, R B (Heidelberg, Max Planck Inst.) ; Cocolios, T E (CERN ; Manchester U.) ; Eliseev, S (Heidelberg, Max Planck Inst.) ; George, S (Michigan State U., NSCL) et al.
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. [...]

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. [...]

$Q$-value and half-lives for the double-$\beta$-decay nuclide $^{110}$Pd
/ Fink, D. (Heidelberg, Max Planck Inst. ; Heidelberg U. ; CERN) ; Barea, J. (Concepcion U.) ; Beck, D. (Darmstadt, GSI) ; Blaum, K. (Heidelberg, Max Planck Inst. ; Heidelberg U.) ; Bohm, Ch.

(CERN) ; Kotila, J. (Yale U.) et al.
The $^{110}$Pd $\beta\beta$- decay ${Q}$-value was measured with the Penning-trap mass spectrometer ISOLTRAP to be ${Q}$ = 2017.85(64) keV. This value shifted by 14 keV compared to the literature value and is 17 times more precise, resulting in new phase-space factors for the two-neutrino and neutrinoless decay modes. [...]
