论文摘要
一氧化氮（NO）的高rydberg状态在40到100之间，生命值超过10 $μ$ S，共振增强了从x $^2π_{1/2} $的X $^2π_{1/2} $的两种颜色的两型两光激光激发，通过A $^2σ^+$中间状态。检测到这些长寿命的rydberg状态中的分子，并通过状态选择性脉冲电场电离激光光激发后的126美元$ $ s表征。将激光激发和电场电离数据合并以构建二维光谱图。这些地图用于识别NO $^+$离子核心的旋转状态，观察到的一系列长寿命的氢化rydberg状态会收敛。结果为Rydberg-Stark的减速和NO静电捕获实验铺平了道路，预计这将进一步阐明这些长期持久的激发态的衰减动力学，并且对在低温下的离子 - 分子反应进行研究很感兴趣。
High Rydberg states of nitric oxide (NO) with principal quantum numbers between 40 and 100 and lifetimes in excess of 10 $μ$s have been prepared by resonance enhanced two-color two-photon laser excitation from the X $^2Π_{1/2}$ ground state through the A $^2Σ^+$ intermediate state. Molecules in these long-lived Rydberg states were detected and characterized 126 $μ$s after laser photoexcitation by state-selective pulsed electric field ionization. The laser excitation and electric field ionization data were combined to construct two-dimensional spectral maps. These maps were used to identify the rotational states of the NO$^+$ ion core to which the observed series of long-lived hydrogenic Rydberg states converge. The results presented pave the way for Rydberg-Stark deceleration and electrostatic trapping experiments with NO, which are expected to shed further light on the decay dynamics of these long-lived excited states, and are of interest for studies of ion-molecule reactions at low temperatures.
