Zusammenfassung
This is a comprehensive book on the topic of atomic structure
calculations of high accuracy. Topics include: experimental
background and basic concepts; angular momentum properties of
wave functions; one-electron atoms; complex atoms --- the
vector model; the $3n-j$ symbols; configuration-average
energies; radial wave equations; radial wave functions and
radial integrals; coupled antisymmetric basis functions;
energy level structure (simple configurations); the algebra of
irreducible tensor operators; energy level structure (complex
configurations); configuration interaction; radiative
transitions (E1); radiative transitions (M1 and E2); numerical
calculation of energy levels and spectra; external fields and
nuclear effects; continuum states --- ionisation and
recombination; highly ionised atoms; rare-earth and transition
elements and statistical distributions. Appendices on physical
constants; units and conversion factors; conversion between
vacuum and air wavelengths; $3-j$ symbols; $6-j$ symbols;
one-electron and total-atom energies; basis functions; matrix
elements and Racah algebra; matrix elements of spherical
harmonics; coefficients of fractional parentage; $U^(k)$,
$V^(kl)$ and relative line strengths within an $LS$
multiplet are also included.
