Doppler-tuned Bragg Spectroscopy of Excited Levels in He-Like Uranium: a discussion of the uncertainty contributions
Martino Trassinelli, Ajay Kumar, H. F. Beyer +4
We present the uncertainty discussion of a recent experiment performed at the GSI storage ring ESR for the accurate energy measurement of the He-like uranium 1s2p3P2- 1s2s3S1 intra…
High-accuracy Complete Active Space multiconfiguration Dirac-Hartree-Fock calculations of hyperfine structure constants of the gold atom
Jacek Bierón, Charlotte Froese Fischer, Paul Indelicato +2
The multiconfiguration Dirac-Hartree-Fock (MCDHF) model has been employed to calculate the expectation values for the hyperfine splittings of the 5d96s2 2D3/2 and 5d96s2 2D5/2 leve…
Measurement of the trapping lifetime close to a cold metallic surface on a cryogenic atom-chip
Andreas Emmert, Adrian Lupascu, Gilles Nogues +3
We have measured the trapping lifetime of magnetically trapped atoms in a cryogenic atom-chip experiment. An ultracold atomic cloud is kept at a fixed distance from a thin gold lay…
Analysis of X-ray spectra emitted from laser-produced plasmas of uranium
J. P. Marques, Paul Indelicato, C. I. Szabo +1
In this paper, we used the multiconfiguration Dirac-Fock method to generate theoretical X-ray spectra for Co-, Ni-, Cu-, Zn-, Ga-, Ge-, As-, Se-, Br-, Kr-, and Rb-like uranium ions…
