ResumoWe report the preparation of a $^{83}\mathrm{Kr}{}^{m}$ source and its use in calibrating a liquid xenon detector. $^{83}\mathrm{Kr}{}^{m}$ atoms were produced through the decay of $^{83}\mathrm{Rb}$ and introduced into liquid xenon. Decaying $^{83}\mathrm{Kr}{}^{m}$ nuclei were detected through liquid xenon scintillation. Conversion electrons with energies of 9.4 and 32.1 keV from the decay of $^{83}\mathrm{Kr}{}^{m}$ were observed. This calibration source will allow the characterization of the response of noble liquid detectors at low energies. $^{83}\mathrm{Kr}{}^{m}$ may also be useful for measuring fluid flow dynamics, both to understand purification in noble liquid-based particle detectors, as well as for studies of classical and quantum turbulence in superfluid helium.
