| 摘 要： | 为进一步研究K介子原子和∑超子原子两类奇异原子中的相互作用和能量问题，具体数值求解了Klein-Gordon方程和Dirac方程，得到K介子原子和∑超子原子的相应能级，结果与实验数据吻合得相当好，其相对误差最大的仅为-0．058％和0．035％，光学模型势应用于奇异原子能级计算能够提高理论结果的准确性。这表明光学势正确地反映了介子或超子与核子之间的强相互作用，并且表明核子间的强相互作用力为吸引力。

| Abstract: | 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. |
