“…These remarks simply serve to emphasize that in classical similarity scaling ͓10͔, ᐉ must be scaled along with n, i.e., the eccentricity held constant ͑see Ref. ͓19͔,Sec. 4.4͒, which is certainly not done when CTMC results for fixed ᐉ are carried without change from nϭ2 or 3 to Rydberg states.…”

Electron capture by Li ϩ ions from aligned Na(25p) Rydberg atoms was measured as a function of the approach angle between the alignment axis of the target-atom wave functions and the ion-beam direction, over a range of reduced velocity ṽ ϭ1.0-2.0, where ṽ ϭv ion /v e . A Stark barrel was used to generate uniform rotatable electric fields over the collision volume and to align Rydberg atoms along the field at arbitrary angles over a full range of 360°. A mixture of Na(25p) fine-structure levels was prepared in the Stark barrel by two-step pulsed laser excitation in the presence of a moderate electric field ͑about 56 V/cm͒ followed by adiabatic switching and rotation to 1.8 V/cm. The relative capture cross section, which varied sinusoidally as a function of the alignment angle, had maxima at 0°and 180°and minima at 90°and 270°throughout this velocity range, showing a strong preference for capture from the endwise arrangement. The alignment effect weakened as the projectile velocity was increased. The Rydberg-state results differ in both magnitude and trend from those based on low-lying aligned states. The spin-independent asymmetry parameter was inferred from the angle-dependent capture cross sections after the spin-orbit depolarization effect in the mixed Rydberg p state was fully accounted for so that the results correspond purely to molecular ⌺ and ⌸ collision geometries.

“…Many scientists have since then been influenced by this misunderstood necessity of smoothing out the unwanted maximum. We refer here to one more example of an important review co-authored by one of our close collaborators, the review of Charge transfer from coherent elliptic states [15]. In their figure 4 the authors show the "smoothed" density introducing it as The probability distribution projected onto the plane of the orbital is concentrated near a classical elliptic path., i.e.…”

For many purposes it is desirable to have an easily understandable and accurate picture of the atomic states. This is especially true for the highly excited states which exhibit features not present in the well known states hydrogen-like orbitals with usual values of the quantum numbers. It could be expected that such visualizations are readily available. Unfortunately, that is not the case. We illustrate the problems by showing several less fortunate earlier presentations in some scientifically most valuable works, and show more suitable visualizations for those cases. The selected cases are not chosen to criticize the authors' approach. Rather, we have taken these very important papers to underline the need for serious work with graphical representations which this work attempts to be a part of.In this text we discuss the problems encountered when visualizing Rydberg states, review some existing presentations and propose guidelines for applications. The focus of this work are so called Stark states and coherent elliptic states of Rydberg atoms. In the sections on elliptic states we show some quite novel geometric interpretations which should be very helpful in analysis of Rydberg state manipulations in external fields.Our demonstration examples involve only hydrogen-like states. However, the techniques and analysis are also relevant for Rydberg molecules and more complicated highly excited atomic and molecular systems.

“…Axially symmetric highly excited states of hydrogen-like systems correspond to the quantum numbers |m| = n −1 >> 1, with m and n being magnetic and principal quantum numbers, respectively. Highly excited states of this symmetry are also called circular Rydberg states (CRS), and they are the subject of lots of theoretical and experimental works, e.g., papers [1][2][3][4][5][6][7][8] and the references therein.…”

We consider classical axially symmetric states of relativistic hydrogenic ions under collinear electric and magnetic fields of arbitrary strengths. For such Rydberg states, we study the role of relativistic effects. Our analytical results demonstrate that the primary outcome of the allowance for the relativism is an increase in the critical value of the electric field at which the ionization occurs.
