Spectral lines, widths, and shapes are powerful tools for emitting/absorbing gas diagnostics in different astrophysical objects (from the solar system to the most distant objects in the universe—quasars). On the other hand, experimental and theoretical investigations of laboratory plasma have been applied in spectroscopic astrophysical research, especially in research on atomic data needed for line shape calculations. Data on spectral lines and their profiles are also important for diagnostics, analysis, and the modelling of fusion plasma, laser-produced plasma, laser design and development, and various plasmas in industry and technology, like light sources based on plasmas or the welding and piercing of metals by laser-produced plasma. The papers from this book can be divided into four groups: 1. stark broadening data for astrophysical and laboratory plasma investigations; 2. applications of spectral lines for astrophysical and laboratory plasma research; 3. spectral line phenomena in extragalactic objects, and 4. laboratory astrophysics results for spectra investigation. The reviews and research papers, representing new research on the topics presented in this book, are of interest for specialists and PhD students. We hope that the present book will be useful and interesting for scientists interested in the investigation of spectral line shapes and will contribute to the education of young researchers and PhD students.

Astrophysics is a branch of space science, wherein the laws of physics and chemistry are applied in order to understand the universe and its components. Spectral line shape refers to the shape of a feature observed in spectroscopy that represents an energy change in an ion, atom or molecule. The shapes and widths of spectral lines are effective instruments for absorbing and emitting gas diagnostics in various astrophysical objects. The absorption and emission lines of astrophysical objects are formed in a variety of kinematical and physical circumstances and at a distance from the observer. Data on spectral lines and their profiles is crucial for modeling, diagnostics and analysis of laser development and design, fusion plasma, and plasma produced through laser. It is also important for various plasmas in technologies such as the piercing and welding of metals by laser-produced plasma and plasma based light sources. This book provides comprehensive insights into the theory of spectral line shapes in astrophysics. Also included herein is a detailed explanation of the various roles and applications of spectral line shapes in astrophysics. This book is a vital tool for all researching and studying this area of astrophysics.

The VI Serbian Conference on Spectral Line Shapes in Astrophysics was about the investigation of spectral line shapes in extragalactic objects, such as, active galactic nuclei, stellar atmospheres, and astrophysical spectra in general. Atomic spectral line shapes in various discharges and plasma devices was also discussed. The main purpose of the Conference was to present and discuss new results found by participants working in this research field, and to review significant topics.

Studies of spectral line shapes, on the fundamental side, reveal the underlying atomic and molecular interactions. On the practical side, they are employed as powerful diagnostic tools for energy pursuit via controlled fusion, for technological gas discharges, for the atmosphere of the Earth, the Sun, and other stars.

The book presents an advanced tool for experimentalists using spectral lineshapes for diagnostics of laboratory or astrophysical plasmas, and for theorists helping the experimentalists in interpreting the experimental line profiles. It significantly expands the scope of parameters of plasmas and/or fields in it that can be measured. For some parameters, the book presents new, more advanced diagnostic methods than the methods covered in the previous books.

New applications of atomic spectroscopy in laser physics, laser spectrosco py, laser frequency and wavelength measurements, plasma physics, astrophysics, and some other related problems have been developed very intensively in the last years. As a result, the approximate methods of calculation of the transition probabilities and cross sections necessary for all these applications have become of vastly increased importance. At the same time, some new problems have arisen in the theory of spectral line broadening such as the shape of nonlinear resonances in the spectra of gas lasers, interference effects, and some other problems connected with various spectroscopic methods of plasma diagnostics. This book is devoted to the systematic treatment of the theory of the elementary processes responsible for the excitation of atomic spectra and the theory of spectral line broadening. The choice of problems is significantly different from that traditional for books on the theory of atomic collisions. The main goal of the book is to present the most efficient and useful of comparatively simple approximate methods for the calcula tion and estimation of cross sections. Numerous tables containing the results of approximate cross section calculations for the most important elementary processes are included in the book. Comprehensive presenta tion of the theory of atomic collisions is out of the scope of this book and can be found elsewhere. However, the fundamentals of the general theory of collisions which are necessary for formulation of approximate methods are given in Chapter 2.
