| dc.description | The separate reactions of the <sup>2</sup>P<sub>3/2</sub> and <sup>2</sup>P<sub>1/2</sub> ground states of Kr<sup>+</sup> with O<sub>2</sub>, CO, N<sub>2</sub>O and OCS have been investigated over the mean relative kinetic energy (E<sub>cm</sub>) range from 0.04 to several eV using a flow-drift tube (FDT) apparatus. The versatility of the technique has permitted state selective ion generation and depletion. Charge transfer has been observed from Kr<sup>+</sup>(<sup>2</sup>P<sub>3/2</sub>) and Kr<sup>+</sup>(<sup>2</sup>P<sub>1/2</sub>) to each neutral reactant with rate coefficients k and k* respectively. Although not previously observed at 300K, collisional Kr<sup>+</sup>(<sup>2</sup>P<sub>1/2</sub>) to Kr<sup>+</sup>(<sup>2</sup>P<sub>3/2</sub>) conversion (quenching) with the neutral reactant is taken into account, since this process can become significant at higher energies, as is demonstrated here in reactions with N<sub>2</sub>O. This is described by a rate coefficient k<sub>q</sub>. Experiments with CO suggested the reverse process of collisional conversion Kr<sup>+</sup>(<sup>2</sup>P<sub>3/2</sub>) to Kr<sup>+</sup>(<sup>2</sup>P<sub>1/2</sub>) also takes place above the necessary energy threshold. Experimental result (for the reactants shown) are presented for k(O<sub>2</sub>, N<sub>2</sub>O and OCS), k* (OCS) and k<sub>t</sub> (N<sub>2</sub>O, O<sub>2</sub> and OCS, where k*<k<sub>f</sub><k*+k<sub>q</sub>) over the accessible E<sub>cm</sub> range. |
