本文采用光学-光学双共振技术，以B (3)Πu （0(u)）价态（v(B) = 19）为中间态，直接观测到e0 (g) + ((3)P2) (v(E) = 0 - 3) I2离子对态的远红外放大自发辐射。在19 ~ 28 μm波长范围内检测到的定向远红外发射归因于e0 （g) + (3)P2）离子对态向d0 （u) + (3)P2）离子对态的振动跃迁。我们还观察到d0 (u) + ((3)P2)态的紫外荧光，该荧光不仅包括由放大的自发发射填充的振动能级，还包括由碰撞能量转移填充的振动能级。对d0 （u) + (3)P2）态的振动分布分析表明，在我们的实验条件下，通过放大的自发发射进行的种群迁移占主导地位。
We report direct observation of far-infrared amplified spontaneous emission from the E 0(g)⁺ ((3)P2) (v(E) = 0 - 3) ion-pair state of I2 by using an optical-optical double resonance technique with the B (3)Πu (0(u)⁺) (v(B) = 19) valence state as the intermediate state. The directional far-infrared emission detected in the wavelength range from 19 to 28 μm was assigned to the vibronic transitions from the E 0(g)⁺ ((3)P2) ion-pair state to the D 0(u)⁺ ((3)P2) ion-pair state. The subsequent UV fluorescence from the D 0(u)⁺ ((3)P2) state was also observed, which consists not only from the vibrational levels populated by the amplified spontaneous emission but also from those populated by collisional energy transfer. Analyses of the vibrational distribution in the D 0(u)⁺ ((3)P2) state revealed that the population transfer through the amplified spontaneous emission was dominant under our experimental conditions.
