Extrapolated ionization ranges are presented for H<sup>+</sup> ions of energy 5 to 50 keV in the gases A, CO<sub>2</sub>, N<sub>2</sub>; these show good agreement with measurements by other authors. Further preliminary measurements of ranges for H<sup>+</sup> ions of energy 5 to 50 keV in CH<sub>4</sub>, C<sub>2</sub>H<sub>2</sub>, C<sub>2</sub>H<sub>4</sub>, C<sub>3</sub>H<sub>8</sub>, C<sub>4</sub>H<sub>10</sub>, and for N<sup>+</sup> ions of energy 5 to 30 keV in CH<sub>4</sub>, are presented with an accuracy of ±8%. Estimates of stopping cross-sections of CH<sub>4</sub>, C<sub>2</sub>H<sub>2</sub>, C<sub>2</sub>H<sub>4</sub>, C<sub>3</sub>H<sub>8</sub>, C<sub>4</sub>H<sub>10</sub> for H<sup>+</sup> ions, made from these data, have values in the range 20×10<sup>−15</sup> ev cm<sup>2</sup> to 76×10<sup>−15</sup> ev cm<sup>2</sup>. |
