论文摘要
我们报告了NO和CO在NO和CO的分离片段的三个电荷，双原子离子离子的碎片化动力学，使用后坐力动量光谱仪，在200 KeV质子束的影响下进行了多个电离和CO的分离片段化。获得了各种片段化通道的动能释放分布（KERD）。我们还计算了无^{3+}和CO^{3+}分子离子的几个激发态的势能曲线（PEC）。在计算出的PEC的背景以及简单的库仑激发模型中讨论了所获得的kerds。不稳定前体分子离子的库仑破裂显示了对N^{2+}+ O^+（和C^{2+}+ O^+）片段化通道的明显偏好。
We report on the fragmentation dynamics of triply charged, diatomic, molecular ions of NO and CO. Dissociative fragmentation after multiple ionization of NO and CO is studied under the impact of 200 keV proton beam using recoil-ion momentum spectrometer. Kinetic Energy Release distributions (KERDs) for various fragmentation channels were obtained. We have also calculated the potential energy curves (PECs) for ground and several excited states of NO^{3+} and CO^{3+} molecular ion. The obtained KERDs are discussed in the background of the calculated PECs as well as the simple Coulomb excitation model. Coulomb breakup of the unstable precursor molecular ion shows a clear preference for the N^{2+} + O^+ (and C^{2+} + O^+) fragmentation channel.
