Abstract：
The dynamics of the N-Y system with S=－1 is re-solved,and the spurious resonances in the former calculation are removed.By using the double Fourier transformation,the GCM kernels are transformed into RGM kernels,and then,the effective local N-Y potentials with S=－1 is calculated.It is shown that these potentials are similar to that of Yamamoto's obtained by using the OBE model with phenomenological hard cores.With these potentials,the phase shifts and cross sections of the system can be re-produced.
