考虑有限核质量，研究了氦原子在超强磁场中的电磁跃迁几率。我们解决的制度$\ensuremath{\gamma}=100--10000\mathrm{a}。\ mathrm{u}.$研究每个对称的几个激发态，即，对于磁量子数0，1，2，3，正z宇称和负z宇称，以及单重态和三重态对称。振子强度作为磁场的函数，特别是，有限的核质量上的振子强度的影响示出和分析。
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 $\ensuremath{\gamma}=100--10000\mathrm{a}.\mathrm{u}.$ studying several excited states for each symmetry, i.e., for the magnetic quantum numbers $0,\ensuremath{-}1,\ensuremath{-}2,\ensuremath{-}3,$ 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.
