Hartee-Fock calculations for medium-Z atoms in strong magnetic fields — •Dirk Engel, Jörg Main, and Günter Wunner — 1. Institut für Theoretische Physik, Universität Stuttgart, 70550 Stuttgart

We present an enhanced algorithm to compute energy levels and oscillator strenghts of astrophysically relevant atoms and ions in the range Z=2,…,26 at neutron star magnetic field strenghts in different ionization stages. The Hartree-Fock equations are solved using finite element and B-spline techniques. Excited Landau levels are included to calculate electrons close to the nucleus more accurately and to extend the range of the magnetic fields to smaller strengths.
