Besides the well known Stark resonances, which are localized in the potential well and tunnel through the potential barrier created by the dc-field, "strange" long and short-lived resonances are analytically obtained. These resonances are not localized inside the potential well. We show that the narrow ones are localized above the potential well. These narrow resonances give rise to a {\it peak structure} in a 1D scattering experiment. We also show that the broad overlapping resonances are associated with the static electric field potential barrier. These "strange" overlapping resonances do not give rise to a {\it peak structure} in a 1D scattering experiment. We propose a 2D experimental set-up where in principle these short-lived states should be observed as {\it peaks}. Broad overlapping resonances, associated only with the static electric field potential barrier, could also have observable effects in a $N>1$ array of quantum wells in the presence of a truncated static electric field. This last problem is associated with the resonance tunnelling phenomena which are used in the construction of resonance-tunnelling diodes and transistors.

Measurement and numerical calculation of Rubidium Rydberg Stark spectra
本文报道了用电磁感应透明（EIT）方法测量静态电场中$^{87}$ Rb里德伯原子的斯塔克位移能级。电场强度高达500 V/cm，范围超过经典的电离阈值，使用电极内的玻璃细胞与铷蒸汽。在高信噪比下得到了主量子数$n=35$和$n=70$的Stark图，并与[M. L. Zimmerman等人，Phys. Rev. A 20，2251（1979）]，其最初仅针对$n=15$周围的状态进行验证。我们还计算了低位态和斯塔克位移里德堡态之间的偶极矩阵元，给出了EIT信号相对强度的理论估计。本文的工作在高主量子数和高电场范围内扩展了该数值方法的实验验证，其精度可达2 MHz。
Probing interactions between Rydberg atoms with large electric dipole moments in amplitude modulated electric fields
实验研究了主量子数为$n=53$的里德堡-斯塔克态氦原子间的偶极-偶极相互作用，以及由诱导电偶极矩约为7900 D引起的近似线性斯塔克能移.实验在脉冲超音速亚稳态氦束中进行，粒子数密度高达$\sim10^9$ cm $^{-3}$。在振幅调制，射频电场的存在下，已观察到的光谱强度分布的变化与过渡到这些状态，归因于偶极-偶极相互作用内的合奏激发原子。实验结果与用Floquet方法计算的里德伯能级结构非常吻合，激发最多可由4个原子共享。使用这些里德堡-斯塔克态作为传感器的非共振宽带射频电噪声进行了讨论。
