报道了自由基C D 3 和C D 2 电离的绝对截面和质谱裂解模式。由于自由基的高反应性，此类数据以前从未测量过。在这项工作中，通过快离子束的电荷转移中和产生纯自由基束，并被交叉电子束电离。通过这种方法，可以获得质量选择的母离子和碎片离子的完整收集，从而可以测量定量横截面。
Absolute cross sections and mass-spectral cracking patterns are reported for ionization of the free radicals C D 3 and C D 2. Such data for free radicals have previously been unmeasured because of their high reactivity. In this work, a beam of pure free radicals is generated by charge-transfer neutralization of a fast ion beam and is ionized by a crossed electron beam. With this approach, complete collection of mass-selected parent and fragment ions is obtained, permitting measurement of quantitative cross sections.
