Phys. Rev. A 68, 052703 (2003) [5 pages]Thermal energy charge transfer between S2+ and H2, N2, and COReceived 21 April 2003; published 5 November 2003 We measured the charge transfer rate coefficients for the reactions S2++H2→products, S2++N2→products, and S2++CO→products using a radio frequency trap. S2+ ions are produced by laser ablation of a solid tungsten disulfide target. We derive the rate coefficient of the reaction from the decay rate of the stored ions in the trap. The rate coefficients for the above three reactions are 1.58(0.13)×10-9cm3s-1 at Tequiv=1077K, and 1.67(0.12)×10-9 and 1.78(0.13)×10-9cm3s-1 at Tequiv=6462K. © 2003 The American Physical Society URL:
