本文报道了在制备E_0（g）（+）态的单振转能级时，产生D_0（u）（+）-X（1）σ（g）（+）发射过程的结果。我们的研究表明，两种过程填充D 0（u）（+）状态，哪一个发生取决于实验条件。一个过程涉及E0（g）（+）态的放大自发辐射。另一种是自猝灭中的碰撞诱导能量转移。我们区分这两个过程的荧光信号的时间曲线。这些过程在D 0（u）（+）态中给出了与E0（g）（+）态的给定振转能级完全不同的振动分布。对E_0（g）（+）--> D_0（u）（+）弛豫的结果与前人的结果之间的差异作了简要的讨论。
This paper reports the results of processes resulting in D0(u) (+)-X (1)Sigma(g) (+) emission when a single rovibrational level of the E0(g) (+) state is prepared. Our study reveals that two kinds of processes populate the D0(u) (+) state; which one occurs depends on the experimental conditions. One process involves amplified spontaneous emission from the E0(g) (+) state. The other is collision-induced energy transfer in self-quenching. We distinguish these two processes from the time profiles of fluorescence signals. These processes give completely different vibrational distributions in the D0(u) (+) state from a given rovibrational level of the E0(g) (+) state. The discrepancy between our results and previous results for the E0(g) (+)-->D0(u) (+) relaxation is briefly discussed.
