Fig. 8

The estimated positron trapping coefficients into small clusters (a) and large helium-vacancy clusters (b) plotted as a function of the irradiation temperature. The shaded areas in the right figure illustrate the range of irradiation temperatures with dominantly increasing (dark grey) and dominantly decreasing (light grey) nHe/nV ratio.
