核上A（π，η）X单举反应

Inclusive(π,η) Reactins on Nuclei

利用Ｎ＊（１５３５）共振道模型，在ＤＷＢＡ框架下分析计算了核上Ａ（π，η）Ｘ单举产生反应，具体给出了１２Ｃ（π，η）Ｘ单举反应的双重微分截面，得到与实验符合较好的结果，给出了Ｎ＊－Ｎ之间是相互吸引作用的结论．计算还发现对于η产生过程，泡利原理的限制是不明显的．

By assuming that the ηN reaction is dominated by the N(1535)resonance,the A(π,η)X inclusive reaction is studied in the framework of the DWBA model,and double differential cross sections are calculated for the 12C(π,η)X inclusive reaction.A good agreement between our theoretical result and the experimental datais achieved,and it is found that the interaction between N and N is attractive.The Pauli blocking effect is not obvious for the η production process.
