Abstract

We consider classical circular Rydberg states of a hydrogenic atom/ion under collinear electric and magnetic fields of arbitrary strengths, the entire system being immersed into a plasma with the Debye screening. In this way we add a “new dimension” to the results of the previous paper of one of us, where the screening was not taken into account. We show in detail how the screening decreases the value of the critical electric field required for the ionization at different values of the magnetic field. Our results should have a fundamental importance because hydrogenic atoms/ions under external fields remain a test-bench for atomic physics. Also our results could motivate experiments on the magnetic control of the “continuum lowering” in cold Rydberg plasmas, this being of practical importance.

氢系统圆形里德堡态的德拜屏蔽在任意强度的共线电场和磁场中的作用

摘要

我们考虑在任意强度的共线电场和磁场下,氢原子/离子的经典圆形里德堡态,整个系统通过Debye屏蔽沉浸到等离子体中。这样,我们为我们其中一位成员的前一篇论文的结果添加了一个“新维度”,其中没有考虑筛选。我们详细显示了屏蔽如何在不同的磁场值下降低电离所需的临界电场值。我们的结果应该具有根本的重要性,因为外部场下的氢原子/离子仍然是原子物理学的测试平台。同样,我们的结果可能会激发对冷里德伯格等离子体“连续降低”的磁控制实验,这具有实际意义。
