Charge radii and electromagnetic moments of Bi 214 − 218 : Exploring the “southern” border of the Z > 82 octupole-deformation region

Anatoly E. Barzakh, Andrei N. Andreyev, Zhenxing Yue, L. Nies et autres

The changes in the mean-squared charge radii relative to Bi 126 209 ( δ 〈 r 2 〉 N , 126 ) and the magnetic dipole and electric quadrupole moments in Bi 214 − 218 have been measured using the in-source resonance-ionization …

Extending the low- Z “border” of the A = 100 region of deformation with precision mass spectrometry of Kr 96 − 98

David Lunney, V. Manea, Mathilde Mougeot, L. Nies et autres

The onset of collective nuclear behavior in the $N=60$, $A\ensuremath{\approx}100$ region is examined through high-precision mass measurements of $^{96\ensuremath{-}98}\mathrm{Kr}$, performed with the ISOLTRAP mass spectrometer at ISOLDE, CERN. Our results for $^{96\ensuremath{-}97}\mathrm{Kr}$ agree with previous measurements, with our new $^{97}\mathrm{Kr}$ Penning-trap mass …

A. E. Barzakh, A. N. Andreyev, Z. Yue, L. Nies et autres

The changes in the mean-squared charge radii relative to 209Bi126(𝛿⁢⟨𝑟2⟩𝑁,126) and the magnetic dipole and electric quadrupole moments in 214−218Bihave been measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). Magnetic moments of odd-odd bismuth nuclei have been analyzed by the …

Further Evidence for Shape Coexistence in Zn79m near Doubly Magic Ni78

L. Nies, L. Cañete, D. D. Dao, S. Giraud et autres

Isomers close to doubly magic $_{28}^{78}{\mathrm{Ni}}_{50}$ provide essential information on the shell evolution and shape coexistence near the $Z=28$ and $N=50$ double shell closure. We report the excitation energy measurement of the $1/{2}^{+}$ isomer in $_{30}^{79}{\mathrm{Zn}}_{49}$ through independent high-precision mass measurements with …

Further evidence for shape coexistence in $^{79}$Zn$^{m}$ near doubly-magic $^{78}$Ni

L. Nies, L. Cañete, D. D. Dao, S. Giraud et autres

Isomers close to doubly magic _{28}^{78}Ni_{50} provide essential information on the shell evolution and shape coexistence near the Z=28 and N=50 double shell closure. We report the excitation energy measurement of the 1/2^{+} isomer in _{30}^{79}Zn_{49} through independent high-precision mass measurements with …

Examining the N = 28 shell closure through high-precision mass measurements of Ar 46 – 48

M. Mougeot, D. Atanasov, C. Barbieri, K. Blaum et autres

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

First Glimpse of the N=82 Shell Closure below Z=50 from Masses of Neutron-Rich Cadmium Isotopes and Isomers

V. Manea, J. Karthein, D. Atanasov, M. Bender et autres

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 …

Characterization of the Ho163 Electron Capture Spectrum: A Step Towards the Electron Neutrino Mass Determination

P. C.-O. Ranitzsch, C. Hassel, Mathias Wegner, Daniel Hengstler et autres

The isotope $^{163}\mathrm{Ho}$ is in many ways the best candidate to perform experiments to investigate the value of the electron neutrino mass. It undergoes an electron capture process to $^{163}\mathrm{Dy}$ with an energy available to the decay, ${Q}_{\mathrm{EC}}$, of about 2.8 keV. …
