Our values are 2.4 ± 0.2 <b>×</b> 10<sup>−9</sup> cm<sup>3</sup> s<sup>−1</sup> for H<sub>2</sub>, 6.3 ± 0.9 <b>×</b> 10<sup>−9</sup> cm<sup>3</sup> s<sup>−1</sup> for CH<sub>4</sub>, 4.0 ± 0.3 <b>×</b> 10<sup>−9</sup> cm<sup>3</sup> s<sup>−1</sup> for N<sub>2</sub> and 4.7 ± 0.4 <b>×</b> 10<sup>−9</sup> cm<sup>3</sup> s<sup>−1</sup> for CO. The values are obtained at equivalent temperatures of 1200–2400 K.</p> cm;CH 4 number densities;CH 4 pressures;co;equivalent temperatures;N 2;charge transfer rate coefficients;ion population decay;decay rates;Atomic Physics;Molecular Physics 2013-09-06
