  mesonic atom
In calculating the hyperfinestructure interaction between aμ-mesonic atom and a valence electron, the former can be treated as a pseudonucleus of charge (Z-1), since its radius is very small as compared to the one of the electronic wave function.
      
Mesonic atom production in high-energy nuclear collisions
      
The production probability ofπ-mesonic atom in high-energy nuclear collisions is estimated by a coalescence model.
      
In an attempt to get a deeper insight into the problem of the ? missing X-rays ? in the capture ofμ-mesons in the light elements, a complete cascade calculation of theμ-meson transitions in the mesonic atom was conducted.
      
  mesic atom
The advanced adiabatic approach (AAA) previously proposed for the description of collision problems in atomic physics is extended to the specific case of mesic atom collisions in excited states n?2.
      
From a comparison with the nuclear quadrupole moment measured in the mesic atom Sternheimer shielding factors are calculated.
      
We have measured the rates of the processes μd+ZY→→μSY+d, in which the μp--meson is transferred from a μd mesic atom to an atomzY of higher atomic number (zY stands here for helium, nitrogen, neon, argon, krypton and xenon).
      
The effects of spin and of nuclear interactions are ignored, and also the effect of the outer electrons in a mesic atom is neglected.
      
We have observed the rates of the reaction μp+Y→μY+p where negative muons are transferred from a μp mesic atom to a monoatomic element Y mixed to gaseous hydrogen at 26 atmospheres.

The radiative capture of μ-meson by proton is treated by using the renor-malized universal Fermi interaction of V-A type and Zeldowich's theory of μ mesic hydrogen. Contrary to the result of Lee, Huang and Yang, it is found that, if the effect of the strong interaction is neglected, then it is impossible for photon being emitted during the capture. The influence of the strong interaction consists of two respects, namely: the effect of the magnetic moment of the nucleon and the renormalization effect on the universal...

The radiative capture of μ-meson by proton is treated by using the renor-malized universal Fermi interaction of V-A type and Zeldowich's theory of μ mesic hydrogen. Contrary to the result of Lee, Huang and Yang, it is found that, if the effect of the strong interaction is neglected, then it is impossible for photon being emitted during the capture. The influence of the strong interaction consists of two respects, namely: the effect of the magnetic moment of the nucleon and the renormalization effect on the universal Fermi weak interaction. The effect of the anomalous magnetic moment is negligible. However, the contribution of proton to the emission of photon is not at all small in comparison with that of the μ-meson duo to the renormalization effect on the universal Fermi weak interaction. As a result, the photons emitted are no longer 100% right hand polarized. It is estimated, that only 80% of the photons has a spin parallel to its momentum. The radiative capture rate of the μ-meson by proton is 1/(1.6×105) of the

本文利用重正化了的费米型V-A弱相互作用计算μ介子被质子吸收时所产生的辐射俘获现象。在计算中利用了余列多维奇等所指出的μ介子在俘获前停留在K层的单重态上的理论结果。计算的结果与李政道等忽略强相互作用的影响及忽略μ介子原子由三重态至单态的跃迁所得到的结果有很大的不同。我们得到当完全不考虑强相互作用的影响时μ介子被质子俘获时不能放出γ辐射的结论。其次我们考虑了两方面的强相互作用影响,一方面考虑了核子反常磁矩的影响,另一方面又考虑了强相互作用对V-A弱相互作用的重正化效应。计算结果指出:反常磁矩的贡献只为重正化效应的5%左右。由重正化效应所产生的辐射俘获几率只有李政道等所给出的几率的14%,放出的光子不再是100%右旋的,估计约有20%的左旋光子。

The energy levels of mesic atom and hyperon atom are obtained by solving of the Klein-Gordon equation and Dirac equation numerically. The results coincide with the experimental date well.

The interaction and energies of mesic atom and hyperon atom of both the strange exotic atoms are further studied. The energy levels of mesic atom and hyperon atom are obtained by solving of the Klein-Gordon equation and Dirac equation numerically. The results coincide with the experimental date well. The maximum fractional errors are -0.058% and 0.035% respectively. The optical model is applied to the calculation of energy levels of the strange exotic atoms can increase the correctness of the theoretical results. It is validity that the strong-interaction between the mesic or hyperon and nucleons is described by the optical model potential in the strange exotic atoms,and it is an attraction between the nucleons.
