摘要/Abstract

摘要： 通过对Σ^-原子的理论分析, 数值求解相应的Dirac方程, 得到一组Σ^-原子的能级值, 与实验数据吻合; 其结果连同K^-原子的情况表明了Batty光学模型势在奇异原子中应用的正确性, 进而表明核子间的强相互作用力为排斥力. 

Abstract: The energy levels of Σ^- atom are obtained by solving the Dirac equation numerically. The calculated result agrees with the relevant experimental data very well. Our result, along with the previous calculation result concerning K^- atom, indicates the validity of the optical model potential to the strange exotic atoms. Moreover, it can be derived from our result that the strong interaction between the nucleons is a repulsive force.

Key words: Dirac equation, Σ^- atom, optical model potential
