TL;DR: In this article, a large-scale shell-model calculation was performed on Zn (Z=30) isotopes at ISOLDE, CERN and the results showed that the dominant term in their wave function was the dominant terms in the wave function of the Iπ 1/2+ isomer.
Journal ArticleDOI
Isotope shift of 40,42,44,48Ca in the 4s2S1/2→ 4p2P3/2 transition

TL;DR: In this paper, improved isotope shift measurements of the isotopes Ca in the (D2) transition using collinear laser spectroscopy were reported, with an uncertainty of 5-10%.
Journal ArticleDOI
High-resolution laser spectroscopy of 27-32Al

TL;DR: For the first time, mean-square charge radii of radioactive aluminum isotopes have been determined alongside the previously unknown magnetic dipole moment of $^{29}$Al and electric quadrupole moments of $€ 29,30}€Al.
Journal ArticleDOI

TL;DR: A linear Paul trap for cooling of ion beams, the former cooler for emittance elimination radiofrequency quadrupole (RFQ) at MISTRAL/ISOLDE, has been installed and commissioned at the TRIGA-SPEC experiment located at the research reactor.
Journal ArticleDOI

TL;DR: In this article, the hyperfine transitions in lithium-like and hydrogen-like bismuth were remeasured by direct laser spectroscopy at the experimental storage ring and a voltage divider was employed to monitor the electron cooler voltage in situ.
