Abstract：
The strength of π-nucleus double charge exchange reaction is related to the spectroscopic factor of two nucleon transfer. In this paper, the relationship between the reaction amplitude and the spectroscopic factors is discussed. As an example, two kinds of nuclear structure are used in discussing the excitation function and the differential cross section of ²⁶Mg(π⁺, π^－)²⁶Si. It is shown that the theoretical method can explain the exprimental data.
