摘要：

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 B=0-100 a.u. 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.
