Electron–ion collisions: Fundamental processes in the focus of applied research
TLDR
An overview of the processes involved in electron-ion collisions, their cross sections, the experimental approaches and typical results can be found in this paper, where the present status of the field is discussed and characterized.Abstract:
Electron–ion collisions are among the most important atomic processes in ionized gases. They comprise elastic scattering, excitation, ionization, and recombination. Theoretical approaches are numerous but calculating reliable results for applications is a task that has not generally been solved, although theory has progressed considerably in the last decade and can now provide reference data for electron collisions with few-electron systems. Experimental data on electron–ion collisions can be inferred from plasma observations, from ion trap measurements, from careful preparation and analysis of ion–atom collisions, and from colliding-beams experiments. The spectrum of equipment employed in the measurements ranges from table top size to large accelerator and storage-ring facilities. This article provides an overview of the processes involved in electron–ion collisions, their cross sections, the experimental approaches and typical results. The present status of the field is discussed and characterized by numerous examples illuminating the accomplishments as well as the limitations of experimental access to accurate detailed cross sections and rate coefficients, as they are required for understanding and modelling laboratory or astrophysical plasmas.read more

Nuclear physics with unstable ions at storage rings
TL;DR: In this article, the authors focus on nuclear physics and nuclear astrophysics experiments with in-flight produced exotic ions that were injected into storage-cooler rings, and show that storage-Cooler rings are ideal devices where two-body beta decays of exotic highly-charged ions, such as bound-state beta decay and orbital electron capture, can be studied in every detail, based on single-ion decay spectroscopy.

TL;DR: In the last two decades, a number of nuclear structure and astrophysics experiments were performed at heavy-ion storage rings employing unique experimental conditions offered by such machines as discussed by the authors, and building on the experience gained at the two facilities presently in operation, several new storage ring projects were launched worldwide.
