• The critical shear stress of NaCl single crystals has been measured down to 4.2 K. It is found that the critical resolved shear stress below 77 K increases rapidly with decreasing temperature, as observed for LiF. Analysis shows that the temperature and strain rate dependence of the critical resolved shear stress below 30 K is described in a consistent manner in terms of the theory of the thermally activated double kink formation mechanism of dislocation motion, i.e. the Peierls mechanism. The Peierls stress of NaCl is estimated to be 1.0-1.2 kg/mm^2.
