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

Abstract: In this paper, the disintegration energy spectrum and Cross sections of the highenergy (π±μ) and (K±μ) atoms in screened. conlomb field are calculated usingperturbation expansion of the quantized composite field theory and relativistic B. S.wave functions of (π±μ) and (K±μ) In the extrarelativistic approximation,for a majority of atomic nucleus the disintegration Cross-sections of (π±μ) and (K±μ) 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)→π0+vμ(vμ); K±μ)→K0+vμ(vμ) and π±μ)→μ+-+vμ(vμ(K±μ)→μ++μ-+vμ(vμ) are calculated.
