Abstract：
Under the Glauber approximation, the problem about the theoretical description of the excitation of the 9.5MeV level of ¹³C in π- ¹³C inelastic scattering is discussed. We assume that the transition to the 9.5MeV level is semi-coherent one step process. The weak coupling nucleus model is used for the initial and final nucleus structure. Based on the assumption j=7/2 ⁺and the approximation Γ ^(v) 1/2Γ ^(s), the differential cross section of the inelastic ¹³C (π ^±, π ^′±) ¹³C*(9.5MeV) at T ^lab _π=180MeV is calculated and compared with the existed data. The agreement is not quite satisfactory.
