碘分子E带离子对态的寿命测量

LIFETIME DETERMINATION OF AN ION PAIR STATE IN THE E REGION OF IODINE

采用时间分辩技术，给出了碘分子Ｅ带Ｅ２离子对态（１８≤Ｖ≤２１）的辐射寿命。其值在９．５２至８．７４ｎｓ（Ｊ＝１０８）和８．２２至７．８６ｎｓ（Ｊ＝１０６）之间变化，这些辐射寿命所存在的数学模型上的微小绝对误差说明Ｅ２态的强ｇ／ｕ跃迁可能存在。

In this paper we present the radiative lifetimes of the E 2 ion pair state (18≤V≤21) in the E region of I 2, which range from 9.52 to 8.74 ns (J=108) and from 8.22 to 7.86 ns (J=106) by means of timeresolved techniques. The very small absolute deviations of mathematical modeling of these lifetimes indicate that the strong g/u transition of the E 2 state may exist. This is conducive to interpreting the experimental results qualitatively.
