Abstract

We present a series of time-differential perturbed angular correlation measurements of the time-dependent interaction associated with the aftereffects processes which follow the electron capture decay of the111In embedded in In2O3 precipitates in a silver matrix. The In2O3 precipitates were obtained by internal oxidation of indium-silver alloys. We study the atomic recovery probability dependence on the precipitate size and temperature. We analyze the influence of the surface charge density built-up at the metal semiconductor contact on the electron availability. The experimental results allow us to suggest a tentative description of the recovery processes in the precipitates.
