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 ^-15cm ²and 10 ^-17cm ²respectively. Furthermore, using the same B.S. wave functions above, the decay rate of( π ^± μ ^干)→ π ⁰+v _μ(v _μ); K ^± μ ^干)→ K ⁰+ 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.
