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 ^－18cm ², and the calculation result of the decay rate is w[(π ⁺Ω ^－)→π ⁺Λ ⁰K ^－]/w[Ω ^－→Λ ⁰K ^－]=1+O(α).
