Abstract
TDPAC measurements were carried out in tungsten foils and single crystals using implanted111In as a probe nucleus. After damaging the bcc tungsten lattice by heavy ion implantation, electron- and proton-irradiation the trapping of three different defects in the temperature range 293–1,000 K was observed. They were characterized by quadrupole interaction frequencies of vQ1 = 142(2) MHz, vQ2 = 181(5) MHz and vQ3 = 263(5) MHz. The largest fraction of In nuclei experiencing electric field gradients corresponding to vQ1 and vQ2 was reached at app. 630 K whereas for vQ3 this maximum appeared at app. 850 K. The defect configurations producing the different electric field gradients could be identified as a monovacancy trapped in a nearest neighbour 〈111〉 position (vQ1), a double vacancy consisting of two adjacent vacancies in the nearest neighbour shell of the probe atom (vQ2) and possibly a larger cluster (vQ3).
