Complaints of the April 1997 seminar. The designation applies to exterior static magnetic and/or electrical fields which are sufficiently extreme to reason changes in atomic or molecular constitution and dynamics. Thirty-eight contributions speak about the habit and houses of atoms in robust static fields, the elemental elements and digital constitution of molecules in robust magnetic fields, the dynamics and facets of chaos in hugely excited Rydberg atoms in exterior fields, topic within the surroundings of astrophysical items (white dwarfs, neutron stars), and quantum nanostructures in powerful magnetic fields. individuals hail from such disparate fields as atomic and molecular physics, theoretical chemistry, and astrophysics.

Taking into account that the magnetic field strength varies at least by a factor of two across the surface of a magnetic white dwarf star, it is obvious that most lines are broadened to invisibility in the spectra. However, for magnetic fields stronger than T some of the transitions run through maxima or minima of the wavelength and thus can produce sharp absorption features – the stationary components of the hydrogen atom. On a dense mesh of electric field strengths we calculated the magnetic field strengths, the wavelengths and the oscillator strengths of the extrema of all stationary lines of Lyman Balmer and Balmer – the most important features in the optical and UV region of the spectra.
