Special Issue Information

Dear Colleagues,

Photoionization of an atom or ion is one most common processes involving the interaction of a photon with an atom. It is one of the four most dominant atomic processes, along with photo-excitation, electron-ion recombination, and electron impact excitations, in astrophysical plasmas that produce the spectra and hence carries considerable information about the constituent elements and their abundances, plasma opacity, ionization fractions, etc. This special issue will present the precise underlying science of photoionization. Although direct photoionization via absorption of a photon by the atomic system happens, resonances form in the process as the energy of the photon-atom system matches to that of a doubly excited state, known as the autoionizing state, lying above the ionization threshold. It is inherent to study the process with inclusion of resonances. The objective of this issue is to advance the current understanding of atomic photoionization, both theoretically and experimentally, for complex atomic systems with demonstrations of various features in the low and high energy regions, that will impact the accuracy of photoionization environments, modeling of astrophysical and laboratory plasmas and their applications.

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 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.
