Using a combination of the bond formalism with the recursion method of calculating the Green's function of hole moving in the antiferromagnet (AF) spin 1/2 background we evaluate the energy of a single bond‐centered, bond‐ordered stripe and compare with the energy of a site‐centered stripe. By taking into account the width change of AF domains separated by hole‐rich domain walls (DWs) we find that the crossover between the phase of site‐centered stripes and the phase of bond‐centered stripes takes place upon doping the 2D spin 1/2 AF.
