Abstract The difference of spectral statistics properties between single-j and two-j shell models has been studied in the frame of the cranking model. The results show that the system becomes more regular when single-j space (i_13/2) is replaced by a two-j shell (g_7/2+d_5/2), although the basis size of the configuration space is unchanged. However, the degree of chaos of the system changes slightly when configuration space is enlarged by extending the single-j shell (i_13/2) to two-j (i_13/2 +g_9/2) shell.
