Abstract：
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.
