Abstract
The electronic structure of the ground state and some excited states of neutral atoms with the nuclear charge numbers and their singly positive ions are investigated by means of our two-dimensional mesh Hartree-Fock method for strong magnetic fields For the ground-state configurations of all the atoms and ions considered are given by fully spin-polarized configurations of single-electron orbitals with magnetic quantum numbers ranging from to where N is the number of the electrons. Focusing on the fully spin-polarized situation, we provide critical values of the magnetic-field strength for which crossovers with respect to the spatial symmetries of the ground state take place. It is found that the neutral atoms and singly charged positive ions with have one fully spin-polarized ground-state configuration, whereas for one intermediate fully spin-polarized configuration with an orbital of type occurs.
