The Hartree-Fock method with single-particle wavefunctions adapted in symmetry to the respective regimes, i.e. spherical wavefunctions for dominating Coulomb forces ( beta <sub>z</sub>=B/(Z<sup>2</sup>4.7010*10<sup>5</sup> Tesla)<or approximately=1) and cylindrical wavefunctions for dominating Lorentz forces ( beta <sub>z</sub>>or approximately=1), has been employed to determine wavefunctions, energies and oscillator strengths of helium-like atoms for magnetic field strengths in the range 4.7*10<sup>1</sup> to 4.7*10<sup>8</sup> T. In addition, the problem of level correspondence between the low-field and high-field domains is solved.
