论文摘要
研究了由单能电子激发的乙炔的光发射光谱在190 nm至660 nm的范围内进行了研究。与电子撞击引发的离子激发相关的解离激发和分离电离是有助于光谱的主要过程。频谱由CH，CH，CH+和C2的原子线H，C和分子带主导。除了离散过渡外，我们还检测到了乙基自由基C2H的连续发射辐射。对于频谱的大多数重要线和频段，我们已经测量了绝对激发发射横截面，并确定了特定解离通道的能量阈值。
The optical emission spectrum of acetylene excited by monoenergetic electrons was studied in the range of 190 nm to 660 nm. The dissociative excitation and dissociative ionization associated with excitation of the ions initiated by electron impact were dominant processes contributing to the spectrum. The spectrum was dominated by the atomic lines H, C and molecular bands of CH, CH, CH+, and C2. Besides the discrete transitions, we have detected the continuum emission radiation of ethynyl radical C2H. For most important lines and bands of the spectrum we have measured absolute excitation-emission cross sections and determined the energy thresholds of the particular dissociative channels.
