在294K下，测量了1·160%和2·892%氢-霓离子混合物的电子漂移速度，EI-N值从0.12到1.7Td。这些测量对氢的v=0→1振动激发截面的阈值区域高度敏感，并且比使用H2−He和H2−Ar混合物的漂移速度数据能够对所提出的截面进行更确定的测试。给出了→等人的v=0-1振动激发截面。(1987)被证明与目前的测量不相容。在纯氢和氢气混合物中，根据现有的电子群测量，得到了一组新的氢截面。
Measurements of electron drift velocities have been made in 1·160% and 2·892% hydrogen-neon mixtures at 294 K and values of EI N from 0·12 to 1·7 Td. The measurements are highly sensitive to the region of the threshold of the v = 0 → 1 vibrational excitation cross section for hydrogen and have enabled more definitive tests of proposed cross sections to be made than was possible using drift velocity data for H2−He and H2−Ar mixtures. The theoretical v = 0 → 1 vibrational excitation cross section of Morrison et al. (1987) is shown to be incompatible with the present measurements. A new set of hydrogen cross sections has been derived from the available electron swarm measurements in pure hydrogen and hydrogen mixtures.
