Dynamical studies of the recombination of O and O2 to form ozone are reviewed. The focus is the intriguing isotope dependence of the recombination rate coefficient as observed by Mauersberger and coworkers in the last decade. The key quantity for understanding of this dependence appears to be the difference of zero-point energies of the two fragmentation channels to which excited ozone can dissociate, i.e., X + YZ <-- XYZ* --> XY + Z, where X, Y, and Z stand for the three isotopes of oxygen. Besides the isotope dependence, the variation of the recombination rate coefficient with pressure and temperature is also addressed. Despite the numerous approaches of recent years, the recombination of ozone is far from being satisfactorily explained; there are still several essential questions to be solved by detailed theoretical analysis. We mainly discuss--and critically assess--the results of our own investigations of the ozone kinetics. The work of other research groups is also evaluated.

The ground and some excited states of the Li atom in external uniform magnetic fields are calculated by means of our two-dimensional mesh Hartree-Fock method for field strengths ranging from zero up to 2.35 ϫ10 8 T. With increasing field strength, the ground state undergoes two transitions involving three different electronic configurations: for weak fields, the ground-state configuration arises from the field-free 1s 2 2s configuration; for intermediate fields, it arises from the 1s 2 2p Ϫ1 configuration, and in high fields, the 1s2 p Ϫ1 3d Ϫ2 electronic configuration is responsible for the properties of the atom. The transition field strengths are determined. Calculations on the ground state of the Li ϩ ion allow us to describe the fielddependent ionization energy of the Li atom. Some general arguments on the ground states of multielectron atoms in strong magnetic fields are provided.

The electronic structure of the ground and some excited states of neutral atoms with the nuclear charge numbers 1 ≤ Z ≤ 10 and their single positive ions are investigated by means of our 2D mesh Hartree-Fock method for strong magnetic fields 0.5 ≤ γ ≤ 10000.
