New results on atomic masses and nuclear decay rates from experiments at FRS-ESR (2009)

C. Scheidenberger, F. Attallah, K. Beckert, P. Beller, F. Bosch, D. Boutin, ...

New experimental results on gross properties of exotic nuclear beams, studied at FRS-ESR, are presented: the direct observation of boundstate beta-decay, half-lives of bare nuclei in isomeric states,...

Comment on the paper "Search for oscillation of the electron-capture decay probability of $^{142}$Pm" at arXiv:0807.0649v1 (2008)

Litvinov, Yu. A., Bosch, F., Winckler, N., Boutin, D., Essel, H. G., Faestermann, T., ...

It is argued that orbital electron-capture decays of neutral $^{142}$Pm atoms implanted into the lattice of a solid (LBNL experiment) do not fulfil the constraints of true two-body beta decays, since...

Isotope shift in the dielectronic recombination of three-electron ^{A}Nd^{57+} (2008)

Brandau, C., Kozhuharov, C., Harman, Z., Müller, A., Schippers, S., Kozhedub, Y. S., ...

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 \delta...

Observation of Non-Exponential Orbital Electron Capture Decays of Hydrogen-Like $^{140}$Pr and $^{142}$Pm Ions (2008)

Litvinov, Yu. A., Bosch, F., Winckler, N., Boutin, D., Essel, H. G., Faestermann, T., ...

We report on time-modulated two-body weak decays observed in the orbital electron capture of hydrogen-like $^{140}$Pr$^{59+}$ and $^{142}$Pm$^{60+}$ ions coasting in an ion storage ring. Using...

Measurement of the $\beta^+$ and orbital electron-capture decay rates in fully-ionized, hydrogen-like, and helium-like $^{140}$Pr ions (2007)

Litvinov, Yu. A., Bosch, F., Geissel, H., Kurcewicz, J., Patyk, Z., Winckler, N., ...

We report on the first measurement of the $\beta^+$- and orbital electron capture decay rates of $^{140}$Pr nuclei with the most simple electron configurations: bare nuclei, hydrogen-like and...

Radiative Electron Capture to Continuum (RECC) in 90AMeV U88+(1s22s2) + N+2 : the Short Wavelength Limit of Electron Nucleus Bremsstrahlung (2007)

Nofal, M., Hagmann, S., Stöhlker, T., Jakubassa-Amundsen, D. H., Kozhuharov, C., Wang, X., ...

We have investigated the relation of forward emission cusp electron spectra and bremsstrahlung for 90AMeV U88+ + N2 at the internal supersonic gas jet target of the ESR storage ring of GSI. We find...

New Mass and Lifetime Measurements of $^{152}$Sm Projectile Fragments with Time-Resolved Schottky Mass Spectrometry (2005)

Litvinov, Yu. A., Bosch, F., Geissel, H., Weick, H., Beckert, K., Beller, P., ...

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 the exotic nuclei...

Isospin Dependence in Odd-Even Staggering of Nuclear Binding Energies (2005)

Laser Cooling and Spectroscopy of Relativistic C 3+ Beams at the ESR ∗ (2004)

U. Schramm, M. Bussmann, D. Habs, M. Steck, T. Kühl, K. Beckert, ...

Abstract. We report on the first laser cooling of a bunched beam of multiply charged C 3+ ions performed at the ESR (GSI) at a beam energy of E = 1.47 GeV. Moderate bunching provided a force...

Radiative recombination of bare Bi83+: Experiment versus theory (2000)

Hoffknecht, A., Brandau, C., Bartsch, T., Boehme, C., Knopp, H., Schippers, S., ...

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 with a bare ion...
