Isotope shifts of natural Sr+ measured by laser fluorescence in a sympathetically cooled Coulomb crystal

Brice Dubost, Romain Dubessy, Benjamin Szymanski +3

We measured by laser spectroscopy the isotope shifts between naturally-occurring even-isotopes of strontium ions for both the $5s{}^2{S}_{1/2}\to 5p{}^2{P}_{1/2}$ (violet) and the…
