Abstract：
In this paper, the coulomb disintegration cross-section and decay rate of the atom (π⁺Ω^－) are calculated by using perturbation expansion of the quantized composite field theory and relativistic B-S wave function for spin (0－3/2) electromagnetic bound system. The disintegration cross-section of the high energy atom (π⁺Ω^－) in screened coulomb field of nuclei is about σ=Z^4/3×2.9×10^－18cm², and the calculation result of the decay rate is w[(π⁺Ω^－)→π⁺Λ⁰K^－]/w[Ω^－→Λ⁰K^－]=1+O(α).
