Beryllium in strong magnetic fields

Abstract

We investigate the electronic structure of the beryllium atom subjected to a strong magnetic field in the regime 0 <= gamma <= 10 a.u. The ground as well as many excited states of spin singlet, triplet and quintet multiplicity covering the magnetic quantum numbers |M|=0,1,3,6 for both positive and negative z-parity are discussed and analyzed. Total and one-particle ionization energies are presented. Transition wavelengths as a function of the field strengths for allowed dipole transitions are provided.
