The system of differential equations, established in Part I, of the density of nonconservatively moving mono‐jogs and of the concentration of excess point defects during plastic deformation has been solved asymptotically as well as numerically. The jog density is a linear function of strain, resulting in a temperature dependent contribution to work‐hardening. The excess point defect concentration reaches a steady state value in a constant strain rate experiment and should be caused by interstitials. The results are discussed in terms of the plastic properties in stage I deformation of alkali halides.
