Excited triplet diene is formed via back electron transfer between radical ion pair within a solvent cage.
处于溶剂笼中的三重态离子自由基对经电子反传，产生激发三重态二烯。

It is suggested that the instability is excited in the low density plasma when the electron beam drift velocities exceed the ion acoustic speed.
不稳定性产生的可能机制是由于电子束穿过低密度本底等离子体的漂移速度超过离子声速而激发起来的。

The target atom or ion may be excited to infinite bound states, auto-ionizing states and adjoint continuum states which can be treated in an unified manner by Multichannel Quantum Defect Theory.
