我们研究了均匀 1.0-T 磁场和 {大约}10 V/cm 的平行交流电场中负离子的光脱离。提出了组合场中分离的理论模型。计算表明，10 V/cm 或更高的场应该会显着减小分离截面中的朗道结构。离子产生并存储在潘宁离子阱中，并由单模染料激光器照射。我们提出了与 S{sup -} 分离的初步结果，显示与模型的定性一致性。还讨论了未来的工作方向。
We investigate photodetachment from negative ions in a homogeneous 1.0-T magnetic field and a parallel ac electric field of {approx}10 V/cm. A theoretical model for detachment in combined fields is presented. Calculations show that a field of 10 V/cm or more should considerably diminish the Landau structure in the detachment cross section. The ions are produced and stored in a Penning ion trap and illuminated by a single-mode dye laser. We present preliminary results for detachment from S{sup -} showing qualitative agreement with the model. Future directions of the work are also discussed.
