The possibility of spin-spin effects that are generated by the static quadrupole moments of two strongly deformed nuclei is investigated. Spin-spin total reaction cross sections ${\sigma }_{\mathrm{ss}}^r$ for the system ${}_{}{}^7{}_{}{}^{}$Li${+}^{11}$B at energies $E_{\mathrm{lab}{(}^7\mathrm{L}\mathrm{i})=30\mathrm{}–}$38 MeV are obtained in coupled-channels calculations which include all the possible sequential and mutual reorientation couplings to the two nuclei in the elastic channel. The values of ${\sigma }_{\mathrm{ss}}^r$ obtained are relatively very small, indicating that spin-spin effects of static nuclear deformation are not important for heavy ions.
