A number of v=0~57 vibration levels were determined and assigned. The levels cover more than 99% of the potential well depth of the state. No evident autoionization was found related to the levels belonging to the 13 g- state above the ionization threshold, implying the distinct character of the doubly excited valence state from the Rydberg states.

并发现13 g-态能级即使超过电离限时亦无明显的自电离倾向，反映了双电子激发态不同于里德堡态的独特性质。13 g-态是碱金属双原子分子电离限以下唯一的3 g-对称性的态和电离限下唯一较纯的双电子激发态，这些结果为分子结构和量子化学的定量研究提供了重要的信息；（2）通过检测Na 3d 3p原子荧光，观察到Na2分子的33 g和43 g+态在3s+3d解离限以上的预解离能级及其转动线宽加宽等。

It shows that The correlation between the two outgoing electron and the ion play a more important role in the mechanism of this ionization. 2. The auger and the autoionization process of the inner shell are theindirect processes of the ionization that correspond the relaxation and the double excitation of the inner shell. Taouil et 〓 guesses that these processes are included in the mechanism of the ionization. The present theoretical results showthat the influences on the inner shell ionization of these processes are notimportant.

说明在内壳层的高非对称的动能区域，被电离电子与离子以及末态两个电子之间的角关联在这个电离动力学机制中扮演了重要的作用 2、内壳层的饿歇过程和自电离过程为间接电离过程，对应于碰后相互作用的离子弛豫和内壳层的双激发，Taouil et al的实验〓认为包括在电离的机制，我们的计算表明它们对内壳层(e，2e)反应的影响并不很重要。
