Abstract

Thermal annealing of Cu- ions in γ-irradiated NaCl:Cu has been observed using optical absorption and thermoluminescence over the range from room temperature to 500 K. The first isothermal measurements of the decay of Cu- ions are presented and indicate that the decay is second order with an activation energy of 0.80 ± 0.07 eV. Recovery of Cu+ ions is two stage process, with an intermediate stage involving neither Cu- or unperturbed Cu+ ions. The isochronal annealing curves were different in unbleached samples and in samples bleached to remove F-centers.
