Special Issue Information
Dear Colleagues,
X-ray spectroscopy plays a decisive role in characterizing quantum transitions in atomic physics with highly charged ions. Its prosperous developments can be traced back to 1980s when highly charged ion sources like the electron cyclotron ion source and the electron beam ion source were invented. To date, various experimental and theoretical methods have become well established to assist in understanding the transitions and collision dynamics of highly charged ions under extremely strong electric fields. On the other hand, with the development of X-ray observation techniques in astrophysics in recent decades, the X-ray emission of highly charged ions has come to be a widely observed diagnostic entity in various hot plasma in astrophysical contexts. To better understand the origin of these particles and the relevant physical processes, a large amount of basic atomic data is required for accurately modeling. This Special Issue is focused mainly on laboratory-based astrophysics and seeks to introduce the development of experimental measurements and theoretical developments in fundamental atomic collision processes with highly charged ions. These include high-resolution X-ray measurements with electron beam ion traps and highly charged ion accelerators, recent progress in the direct measurement of charge exchange state selectivity, as well as electron impact excitation and dielectron recombination processes. The Special Issue aims to present some examples showing the importance of atomic physical data in astrophysical X-ray modeling . This Special Issue will be helpful for astrophysical X-ray studies with next generation of high-resolution X-ray missions.

Manuscript Submission Information
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 submissions that pass pre-check are 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 monthly 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 1500 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.
