Abstract
Alpha decays in the EXO-200 detector are used to measure the fraction of charged and daughters created from and decays, respectively. decays in liquid xenon (LXe) are found to produce ions of the time, while the remainder of the atoms are neutral. The fraction of from decays in LXe is found to be , inferred from the relative rates of and decays in the LXe. The average velocity of ions is observed to decrease for longer drift times. Initially the ions have a mobility of , and at long drift times the mobility is . Time constants associated with the change in mobility during drift of the ions are found to be proportional to the electron lifetime in the LXe.
