摘　　要：应用Glauber理论，对(18)O（π~＋，π^-）、(18)Ne双电荷交换反应进行分析，假定(18)O和(18)Ne由2价核子和4α核心组成，计算了共振区Tx＝164MeV的微分截面。结果表明，理论与实验符合得较好。The double charge exchange reaction on 18~O(π+, π- )'Ne is analyzed by using theGlauber theory and the differential cross section at the region of the 6-resonance (Tπ =164 MeV) is calculated in a model which the 18O and 18Ne are assumed to consist of twovalence nucleons and a core of four a-particles. A good agreement between the theory andexperiments is obtained.
