摘　　要：通过对Σ-原子的理论分析,数值求解相应的D irac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.The energy levels of ∑^- 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 force. the strong interaction between the nucleons is a repulsive
