摘要：

We investigate the electromagnetic transition probabilities for the helium atom embedded in a superstrong magnetic field taking into account the finite nuclear mass. We address the regime gamma=100-10 000 a.u. studying several excited states for each symmetry, i.e., for the magnetic quantum numbers 0,-1,-2,-3, positive and negative z parity, and singlet and triplet symmetry. The oscillator strengths as a function of the magnetic field and, in particular, the influence of the finite nuclear mass on the oscillator strengths are shown and analyzed.
