The fragmentation dynamics of nitrogen trifluoride (NF) in collisions with a 500 eV electron is studied by using a momentum imaging spectrometer. The kinetic energy releases of two-body, three-body, and four-body fragmentation channels of NF (q = 2, 3) are investigated. The fragmentation dynamics of three-body, as well as four-body, dissociation channels is analyzed by the Dalitz plot and the Newton diagram. It is found that for all of the dissociation channels, the fragment including N atom (ion) always shares significant momenta, regardless of whether it is charged. For F atom, however, it is always emitted with negligible momenta.
利用动量成像光谱仪研究了 NF（三氟化氮）在与 500eV 电子碰撞中的碎裂动力学。研究了 NF（q=2,3）的二体、三体和四体碎裂通道的动能释放。通过 Dalitz 图和牛顿图分析了三体和四体解离通道的碎裂动力学。结果表明，对于所有的解离通道，包含 N 原子（离子）的碎片总是具有显著的动量，无论其是否带电。然而，对于 F 原子，它总是以可忽略的动量发射。
