Special Issue Information

Dear Colleagues,

Since atomic collision phenomena are strongly affected by the charge-states of the projectile ions, both equilibrium and pre-equilibrium charge-states of penetrating ions in solid, dense-gas media and plasmas are essential to pure and applied atomic collision studies. As for the equilibrium charge-states, there has been a number of papers, compilations, and databases published in the literature, but there still a few for pre-equilibrium charge-state evolutions especially for heavy ion collisions in low-energy range although they are highly demanded in material science, biological physics, accelerator technology and so on. After recent advances in experiments (target preparations etc.), theories (cross section calculations etc.), as well as simulations (including more advanced models), this Special Issue of Atoms will highlight many kinds of contributions related to charge-state evolutions in ion-atom/solid and plasma collisions, ranging from basic data production, simulation codes and cross sections, to application studies which needs a knowledge of charge-state evolutions and to scope also their future needs.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atoms is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The influence of the charge state q on surface modifications induced by the impact of individual fast, heavy ions on muscovite mica was investigated. Beams of 593 MeV 197Auq+ with well-defined initial charge states over a relatively broad range of values (30 to 51) and at different irradiation geometries were used. At normal incidence, the impact features are rounded protrusions (hillocks) with ≳20 nm in diameter. At grazing angles, besides the hillocks, craters and elongated tails (up to 350 nm-long) extending along the direction of ion penetration are produced. It is shown that the impact features at normal incidence depend strongly on the initial charge state of the projectiles. This dependence is very weak at grazing angles as the ion reaches the equilibrium charge state closer to the surface. At normal ion incidence, the hillock volume scales with q3.3 ± 0.6. This dependence stems largely from the increase in the hillock height, as a weak dependence of the diameter was observed. Full article
