Hartree-Fock studies of atoms in strong magnetic fields

We present comprehensive calculations of the electronic structure of selected first-row atoms in uniform magnetic fields of strength ≤[Formula Presented] G, within a flexible implementation of the Hartree-Fock formalism. Ground-state and low-lying excited state properties are presented for first-row atoms He, Li, C, and ion [Formula Presented]. We predict and describe a series of ground-state quantum transitions as a function of magnetic field strength. Due to its astrophysical importance, highly excited states of neutral He are also computed. Comparisons are made with previous works, where available.
