Laser-induced delayed electron detachment from Si2– stored in an electrostatic ion storage ring was observed on the 10 microsecond time scale. The excitation spectra for photon energies near threshold show well-resolved multipeak structures, which are attributed to rovibronic transitions to the electronic excited state. This structure appears only in the signal measured with the delay. The occurrence of delayed detachment on such a long time scale is unusual for diatomic molecules, suggesting that both the autodetachment and fluorescence are slow.

旋转分辨激发光谱由Si2的慢速电子脱附测量。
选自Si激光诱导延迟的电子脱离2 -观察到在10微秒时间尺度存储在静电离子存储环。接近阈值的光子能量的激发光谱显示出良好解析的多峰结构，这归因于电子振动向电子振动态的电子振动跃迁。这种结构仅出现在经过延迟测量的信号中。对于双原子分子来说，在如此长的时间范围内延迟分离的发生是不寻常的，这表明自分离和荧光都很慢。
