激发态寿命 meaning in English

lifetime of excited state

The experiment populated the excitation state of 64cu via 64ni ( p , ny ) 64cu * reaction and the lifetime of low - lying excitation state of 64cu were determined via the delayed coincidence method between pulse proton beam and de - excitation y rays detected by ge ( li ) detector
Sns ）与ge （ l ）探测器测量退激y射线延迟符合的方法，由时间谱tof峰的中值移动的方法来确定激发态寿命。
Photoluminescence characteristics of four hemicyanine derivatives with similar molecular compositions but different donor - acceptor groups in langmuir - blodgett ( lb ) films have been studied by steady state and time - resolved fluorescence spectroscopies . the study mainly include the aggregation behavior of hemicyanine derivatives in lb films , the influence of the donor - acceptor on the excited level and excited lifetime of the hemicyenine derivatives
