Poster Neutrinoless double beta decay

### Description

The nEXO experiment is a planned tonne-scale liquid xenon time projection chamber (TPC) to search for neutrinoless double beta decay of $^{136}$Xe with a half-life sensitivity beyond $10^{28}$ years. For optimal energy resolution in nEXO, the position- and time- dependent detector response must be calibrated to sufficient precision. Dissolved sources which produce events throughout the full TPC volume are being considered as an alternative to external gamma sources for this purpose. This poster will outline the development of a dissolved $^{127}$Xe source for nEXO, including a demonstration of its use for electron lifetime calibrations in a test TPC, in addition to other candidate sources. Projections of the precision with which such sources could be used to calibrate the charge and light response in nEXO will also be presented.
