本文采用先进的反应显微镜研究了54ev电子冲击下甲烷（e, 2e +）的解离电离。通过测量两个电子和离子在三重重合状态下的终态，确定了离子的种类，并确定了沉积到靶上的能量。碎片离子的种类和动能对母离子的中间态有很强的依赖性。分析了产生不同种类离子的可能衰变途径。
We present in this paper an (e, 2e + ion) investigation of the dissociative ionization of methane by 54 eV electron impact employing the advanced reaction microscope. By measuring two electrons and the ion in the final state in triple coincidence, the species of the ions are identified and the energies deposited into the target are determined. The species and the kinetic energies of the fragmented ion show strong dependence on the intermediate states of the parent ion. Possible decay pathways for the production of different species of ions are analyzed.
