Deyan T. Yordanov,Deyan T. Yordanov,D. L. Balabanski,Jacek Bieron,Mark Bissell,Klaus Blaum,I. Budinčević,Stephan Fritzsche,N. Frömmgen,Georgi P. Georgiev,Ch. Geppert,M. Hammen,Magda Kowalska,K. Kreim,A. Krieger,Rainer Neugart,Wilfried Nörtershäuser,J. Papuga,Stefan E. Schmidt +18 more
TL;DR: The neutron-rich isotopes of cadmium up to the N=82 shell closure have been investigated by high-resolution laser spectroscopy and one essential feature of the spherical shell model is unambiguously confirmed by a linear increase of the 11/2(-) quadrupole moments.
Journal ArticleDOI
Laser spectroscopy measurement of the 2s-hyperfine splitting in lithium-like bismuth
Rodolfo Sánchez,Matthias Lochmann,Matthias Lochmann,R. Jöhren,Zoran Andelkovic,Denis Anielski,B. Botermann,Michael Bussmann,Andreas Dax,N. Frömmgen,Christopher Geppert,Christopher Geppert,M. Hammen,Volker Hannen,T. Kuhl,Yuri A. Litvinov,Rubén López-Coto,Thomas Stöhlker,Richard C. Thompson,J. Vollbrecht,Weiqiang Wen,Christian Weinheimer,Elisa Will,Danyal Winters,Wilfried Nörtershäuser,Wilfried Nörtershäuser +25 more
Journal ArticleDOI
Frequency-comb based collinear laser spectroscopy of Be for nuclear structure investigations and many-body QED tests

TL;DR: In this article, the absolute transition frequencies of stable and short-lived isotopes were measured with a frequency comb in collinear laser spectroscopy at ISOLDE (CERN).
Journal ArticleDOI

Thompson,Johannes Ullmann,Johannes Ullmann,Ch. Weinheimer +26 more
TL;DR: The LIBELLE experiment performed at the experimental storage ring (ESR) at the GSI Helmholtz Center in Darmstadt aims for the determination of the ground state hyperfine (HFS) transitions and lifetimes in hydrogen-like and lithium-like bismuth as mentioned in this paper.
