The possibility of intrinsic stacking faults in the b.c.c. lattice is discussed for a central force model. The existence of stable stacking faults depends on the cut‐off radius of the interatomic potential. For rather small cut‐off radii the model predicts stacking faults. However, we obtain stacking fault vectors different from those predicted by the hard‐sphere model. Further, the asymmetry of the stacking fault energy surface with respect to displacements in ± 〈111〉 directions depends on the cut‐off radius.
