Observation of Non-Exponential Orbital Electron Capture Decays of Hydrogen-Like Pr and Pm Ions
Yu. A. Litvinov, F. Bosch, N. Winckler +37
We report on time-modulated two-body weak decays observed in the orbital electron capture of hydrogen-like Pr and Pm ions coasting in an ion storage…
Isotope shift in the dielectronic recombination of three-electron ^{A}Nd^{57+}
C. Brandau, C. Kozhuharov, Z. Harman +25
Isotope shifts in dielectronic recombination spectra were studied for Li-like ^{A}Nd^{57+} ions with A=142 and A=150. From the displacement of resonance positions energy shifts δE…
Isospin Dependence in the Odd-Even Staggering of Nuclear Binding Energies
Yu. A. Litvinov, T. J. Buervenich, H. Geissel +23
The FRS-ESR facility at GSI provides unique conditions for precision measurements of large areas on the nuclear mass surface in a single experiment. Values for masses of 604 neutro…
Radiative recombination of bare Bi83+: Experiment versus theory
A. Hoffknecht, C. Brandau, T. Bartsch +14
Electron-ion recombination of completely stripped Bi83+ was investigated at the Experimental Storage Ring (ESR) of the GSI in Darmstadt. It was the first experiment of this kind wi…
Direct observation of long-lived isomers in Bi
L. Chen, P. M. Walker, H. Geissel +40
Long-lived isomers in 212Bi have been studied following 238U projectile fragmentation at 670 MeV per nucleon. The fragmentation products were injected as highly charged ions into t…
Measurement of the $β^+$ and orbital electron-capture decay rates in fully-ionized, hydrogen-like, and helium-like Pr ions
Yu. A. Litvinov, F. Bosch, H. Geissel +39
We report on the first measurement of the $β^+$- and orbital electron capture decay rates of Pr nuclei with the most simple electron configurations: bare nuclei, hydrogen-…
New Mass and Lifetime Measurements of Sm Projectile Fragments with Time-Resolved Schottky Mass Spectrometry
Yu. A. Litvinov, F. Bosch, H. Geissel +20
The FRS-ESR facilities at GSI provide unique conditions for precision measurements with stored exotic nuclei over a large range in the chart of nuclides. In the present experiment…
Comment on the paper "Search for oscillation of the electron-capture decay probability of Pm" at arXiv:0807.0649v1
Yu. A. Litvinov, F. Bosch, N. Winckler +36
It is argued that orbital electron-capture decays of neutral Pm atoms implanted into the lattice of a solid (LBNL experiment) do not fulfil the constraints of true two-body…
