<p><strong>Figure 4.</strong> The <sup>4</sup>He<sup>+</sup> ion population decay under different Ne pressures (a) and the corresponding decay rates plotted against Ne number densities (b). The rate coefficient found in (b) is used to estimate <em>k</em><sub>loss</sub> for CH<sub>4</sub>.</p> <p><strong>Abstract</strong></p> <p>We report our measured values for the sum of single and double charge transfer rate coefficients between <sup>3</sup>He<sup>2 +</sup> and H<sub>2</sub>, CH<sub>4</sub>, N<sub>2</sub> and CO. 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>
