| 英文摘要 | Alpha decays in the exo-200 detector are used to measure the fraction of charged po-218 and bi-214 daughters created from alpha and beta decays, respectively. rn-222 alpha decays in liquid xenon (lxe) are found to produce po-218(+) ions 50.3 +/- 3.0% of the time, while the remainder of the po-218 atoms are neutral. the fraction of bi-214(+) from pb-214 beta decays in lxe is found to be 76.4 +/- 5.7%, inferred from the relative rates of po-218 and po-214 alpha decays in the lxe. the average velocity of 218po ions is observed to decrease for longer drift times. initially the ions have a mobility of 0.390 +/- 0.006 cm(2) /(kvs), and at long drift times the mobility is 0.219 +/- 0.004 cm(2) /(kvs). time constants associated with the change in mobility during drift of the po-218(+) ions are found to be proportional to the electron lifetime in the lxe. |
