Charge transfer between ground-state N{sup 2+} and H{sub 2}, N{sub 2}, and CO at electron-volt energies

The charge-transfer rate coefficients for reactions of N{sup 2+}(2s{sup 2}2p{sup 2}P{sup o}) with H{sub 2}, N{sub 2}, and CO are measured using ion storage. A cylindrical rf ion trap was used to store N{sup 2+} ions produced by laser ablation of a solid titanium nitride target. The rate coefficients were derived from the decay rate of the ion signal. The rate coefficients for the above three reactions are 3.38(0.35){times}10{sup {minus}11} cm{sup 3} s{sup {minus}1} at T{sub equiv}=2.9{times}10{sup 3} K, 2.10(0.18){times}10{sup {minus}9} cm{sup 3} s{sup {minus}1} at T{sub equiv}=1.3{times}10{sup 4} K, and 3.37(0.29){times}10{sup {minus}9} cm{sup 3} s{sup {minus}1} at T{sub equiv}=1.3{times}10{sup 4} K, respectively. No theoretical or other experimental values are available at this energy range. {copyright} {ital 1997} {ital The American Physical Society}
