论文摘要
我们提出了一种新的机制，该机制有助于通过脉冲场电离检测光相关的远程Rydberg分子：由远距离rydberg分子的衰减创建的离子产品，从而修改了周围地面原子的激发光谱，并促进了对Rydberg nestem的激发，并促进了rydberg necass的激发。这种离子介导的激发机制先前被称为“库仑抗块”。脉冲场电离通常不会区分远距离Rydberg分子的电离和孤立的Rydberg原子的电离，因此该机制检测到的原子离子的数量与探针体积中存在的远距离Rydberg分子的数量不成比例。通过结合毗长范围rydberg分子的分子水平结构的理论建模，结合了北极氏北方北极状态下的高分辨率UV和RF光谱，理论上的分子水平结构的理论模型，以及我们识别的光疗法的速率模型，我们识别了这些迹象的机制，我们识别了这些迹象的机制。远程rydberg分子结合原子渐近线，呈负较大的变化。
We present a new mechanism contributing to the detection of photoassociated long-range Rydberg molecules via pulsed-field ionization: ionic products, created by the decay of a long-range Rydberg molecule, modify the excitation spectrum of surrounding ground-state atoms and facilitate the excitation of further atoms into Rydberg states by the photoassociation light. Such an ion-mediated excitation mechanism has been previously called "Coulomb anti-blockade". Pulsed-field ionisation typically doesn't discriminate between the ionization of a long-range Rydberg molecule and an isolated Rydberg atom, and thus the number of atomic ions detected by this mechanism is not proportional to the number of long-range Rydberg molecules present in the probe volume. By combining high-resolution UV and RF spectroscopy of a dense, ultracold gas of cesium atoms, theoretical modeling of the molecular level structures of long-range Rydberg molecules bound below nP_3/2 Rydberg states of cesium, and a rate model of the photoassociation and decay processes, we unambiguously identify the signatures of this detection mechanism in the photoassociation of long-range Rydberg molecules bound below atomic asymptotes with negative Stark shifts.
