THE COULOMB DISINTEGRATION CROSS-SECTIONS AND DECAY RATE OF THE RELATIVISTIC ELECTROMAGNETIC BOUND STATES (π^±μ^干) AND (K^±μ^干)

Abstract: In this paper, the disintegration energy spectrum and Cross sections of the highenergy (π^±μ^干) and (K^±μ^干) atoms in screened. conlomb field are calculated usingperturbation expansion of the quantized composite field theory and relativistic B. S.wave functions of (π^±μ^干) and (K^±μ^干) In the extrarelativistic approximation,for a majority of atomic nucleus the disintegration Cross-sections of (π^±μ^干) and (K^±μ^干) are about 10^-15 cm² and 10^-17 cm² respectively. Furthermore, using the same B.S. wave functions above, the decay rate of(π^±μ^干)→π⁰+v_μ(v_μ); K^±μ^干)→K⁰+v_μ(v_μ) and π^±μ^干)→μ⁺+μ^-+v_μ(v_μ(K^±μ^干)→μ⁺+μ^-+v_μ(v_μ) are calculated.
