    "abstract": "We investigate the electromagnetic transition probabilities for the helium\natom embedded in a superstrong magnetic field taking into account the finite\nnuclear mass. We address the regime \\gamma=100-10000 a.u. studying several\nexcited states for each symmetry, i.e. for the magnetic quantum numbers\n0,-1,-2,-3, positive and negative z parity and singlet and triplet symmetry.\nThe oscillator strengths as a function of the magnetic field, and in particular\nthe influence of the finite nuclear mass on the oscillator strengths are shown\nand analyzed.",
