Measurements of the ion fraction and mobility of α- and β-decay products in liquid xenon using the EXO-200 detector

RADIOACTIVITY ²²²Rn, ²¹⁸Po(α); ²¹⁴Pb(β^-); measured Eα, αα-coin from ²²²Rn and ²¹⁸Po decays, time delay between Bi-Po pairs using the EXO-200 detector for two-neutrino double β decay experiments; deduced fraction of charged ²¹⁸Po and ²¹⁴Bi ions, number of Rn-Po pairs, ²¹⁸Po ion drift velocity and mobility in liquid xenon.
