Trade paperback. Condition: Good. Presumed First Edition, First printing. xxiii, [1], 185, and additional papers with various paginations at the back. The papers are in two groups. Group A. addresses accurate multiconfiguration Dirac-Hartree-Fock calculations of atomic structure and radiative properties. Group B. presents rigorous treatment of effects from non-spherical perturbations from the nucleus and external magnetic fields on radiative atomic spectra. The content of these papers are briefly described in the Summary of Publications. This work contains a "Popular Summary" in Swedish, Figures. Footnotes. Formulae. Tables. Bibliography. List of Acronyms. Some illustrations have color. Acronyms. Cover has small edge tear. Author inscription inside front cover. Inscription reads To Charlotte from Jon, Thanks for Everything! Lund 20/10 2016 [with a drawing of a flower]. This was inscribed the day before the author's successful dissertation/thesis defense. This is a thesis on atoms and ions; how the atomic electrons interact with each other, with the nucleus, as well as with external magnetic fields, and ultimately how atomic systems interact with light for the purpose of studying laboratory and astrophysical spectra. This work was performed as the Department of Physics at Lund University and defended on the 21st of October 2016. Dr. Grumer is now an astrophysicist and theoretical atomic physicist at Uppsala University in Sweden. He specializes in fundamental atomic structure calculations with a particular focus on atomic processes in relation to astrophysical spectroscopy to aid in our understanding of stars and their environments, the evolution of chemical elements and the history of the Milky Way, as well as the possible origin of heavy elements in neutron-star merger gravitational wave events. In addition to atomic structure calculations, he also carries out various types of experiments, in particular, of charge-exchange processes in low-energy collisions between iron-peak elements and hydrogen at the cryogenic double electrostatic storage ring, DESIREE, at Stockholm University, Sweden. Furthermore, he works with the management of the VALD atomic and molecular database, and he is also a board member of the Computation Atomic Physics (CompAS) collaboration on the teaching and development of multiconfigurational atomic structure methods and codes. Many of these codes, including the GRASP atomic structure code, are now being developed and regularly updated in a fully open-source fashion under the CompAS GitHub account.
