Experimental determination of the nuclear magnetic octupole moment of ${}^{137}$Ba${}^{+}$ ion

Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2

We perform precision measurements on the 5D${}_{5/2}$ manifold hyperfine intervals of a single trapped ion, ${}^{137}$Ba${}^{+}$. RF spectroscopy is used to measure the hyperfine intervals…
