We report measurements of the charged daughter fraction of Po-218 as a result of the Rn-222 alpha decay, and the mobility of Po-218(+) ions, using radon-polonium coincidences from the U-238 chain identified in 532 live-days of DarkSide-50 WIMP-search data. The fraction of Po-218 that is charged is found to be 0.37 +/- 0.03 and the mobility of Po-218(+) is (8.6 +/- 0.1) x 10(-4) cm(2)/vs.

Abstract
We report measurements of the charged daughter fraction of Po-218 as a result of the Rn-222 alpha decay, and the mobility of Po-218(+) ions, using radon-polonium coincidences from the U-238 chain identified in 532 live-days of DarkSide-50 WIMP-search data. The fraction of Po-218 that is charged is found to be 0.37 +/- 0.03 and the mobility of Po-218(+) is (8.6 +/- 0.1) x 10(-4) cm(2)/vs.File in questo prodotto:
