We consider the cascade neutralization of highly charged ions in the interaction with metal-dielectric film surface at moderate ionic velocities and arbitrary angle of incidence. We use the recently developed micro-staircase model based on the quasi-

The energy necessary for the nanostructure creation by the impact of highly charged ions (charge Z ≫ 1) on solid surface consists of the neutralization energy and the deposited kinetic energy. We analyze the relative importance of these two contrib

In the recent beam-foil experiment, resonances have been observed in decay of the beam-foil excited 2p and 2s states of H-like Fe ions at very large times. Qualitatively, the resonances were explained as a consequence of cascading down from the Rydbe

The appearance of resonances (pronounced maxima at nA = nres) in the probability distributions for the population of the Rydberg state (nA, lA, mA) of multiply charged ions (Z ≫ 1) escaping solid surfaces at intermediate velocities (v ≈ 1 a.u.) i

The two-state vector model is used to investigate the final population of the Rydberg states ( n A ≫ 1 , l A = 0 – 2 , m A = 0 ) of multiply charged ions escaping solid surfaces at intermediate velocities ( v ≈ 1 a.u.). Within the framework of

We used the recently developed time-symmetrized, two-state vector model to investigate the intermediate stages of the electron capture into the Rydberg states ( n A ≫ 1 , l A = 0 − 3 , m A = 0 ) of multiply charged ions SVI, ClVII and ArVIII, wit

We consider the slow highly charged ions impinging upon a metal surface covered with a thin dielectric film, and formation of the surface nanostructures (craters) from the standpoint of the required energy. For the moderate ionic velocities, the size

We present a theoretical study of resonances and thresholds, two specific features of Rydberg-state formation of multiply charged ions ($Z=6,$ 7, and 8) escaping a solid surface at intermediate velocities $(v\ensuremath{\approx}1\mathrm{a}.\mathrm{u}

The ionization dynamics of slow hydrogenlike Rydberg atoms (principal quantum number $n\ensuremath{\gg}1$) approaching solid surfaces is considered via an ion-collection electric field, using an appropriate etalon equation method. The complex energy
