Figure 4
Population ratio n 1/n 2 between the sites 1 and 2 (see Fig. 1) in the course of the annealing procedure under stress of 227 MPa. The circles represent experimental values (see Fig. 2), the solid lines—calculated from Eq. (5) with the best-fit parameters given in Table 1. The dashed lines represent the equilibrium population ratios at the corresponding temperatures.
