Abstract
We investigate the electromagnetic-transition probabilities for the helium atom embedded in a strong magnetic field. In total, approximately 12 000 transitions have been calculated covering a grid of 20 different field strengths in the complete regime The changes of the oscillator strengths with increasing field strength are discussed in detail, addressing both individual transitions and sets of transitions among certain symmetry subspaces. A complete reorganization of the oscillator strengths in the intermediate-field regime is observed.
