The Mobility of Aged Ions in Air

The Mobility of Aged Ions in Air The mobility of air ions produced by x-rays has been measured by the simple Rutherford alternating current method. No change in mobility with age could be detected for ions aged as long as one second. The weighted average of the results gives 1.64 ± 0.05 and 2.25 ± 0.05 cm/sec per volt/cm for the mobilities of positive and negative ions respectively. No completely satisfactory explanation has been found for the continual decrease in the coefficient of recombination with age while the mobility remains unchanged. When moist air from the room was substituted for carefully dried air the mobility dropped to 1.4 and 1.8 cm/sec per volt/cm for positive and negative ions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review American Physical Society (APS)

Abstract

The mobility of air ions produced by x-rays has been measured by the simple Rutherford alternating current method. No change in mobility with age could be detected for ions aged as long as one second. The weighted average of the results gives 1.64 ± 0.05 and 2.25 ± 0.05 cm/sec per volt/cm for the mobilities of positive and negative ions respectively. No completely satisfactory explanation has been found for the continual decrease in the coefficient of recombination with age while the mobility remains unchanged. When moist air from the room was substituted for carefully dried air the mobility dropped to 1.4 and 1.8 cm/sec per volt/cm for positive and negative ions.
