Optical Mass Spectrometry of Cold ${\mathrm{RaOH}}^{+}$ and ${{\mathrm{RaOCH}}_3}^{+}$

M. Fan, C. A. Holliman, X. Shi +5

We present an all-optical mass spectrometry technique to identify trapped ions. The new method uses laser-cooled ions to determine the mass of a cotrapped dark ion with a sub-dalto…
