We present a method to deposit a wide range of radioactive probe atoms on surfaces, without introducing lattice damage or contaminating the surface with other elements or isotopes. In this method, the probe atoms are mass-separated using an isotope s

Perturbed angular correlation, Rutherford backscattering and channelling experiments were conducted to study the lattice location and annealing behaviour of 110 keV hafnium ions implanted into iron single crystals. It was found that a fraction of 11-

Vacancy-hydrogen interaction in molybdenum was investigated by means of the perturbed angular correlation technique, using the isotope 111In as a probe. The complex InV2 turned out to trap up to two hydrogen atoms. Assuming a hydrogen migration energ

Hydrogen-vacancy interaction in tungsten was investigated by means of the perturbed angular correlation technique, using the isotope In-111 as a probe. Hydrogen trapping at an In-111-vacancy cluster manifests itself as a change of the local electric

The local lattice environment of the donor In in CdS is investigated measuring the electric-field gradient at the site of the radioactive probe atom 111In by the perturbed gammagamma angular correlation technique. It is shown that implantation of In

The DPAC technique was applied to measure the quadrupole moments of the 300 ps, 5/2− states in75,77As. The isotopes were implanted in α-Ga. The following results were obtained: Q(5/2−)=30(10) fm2 for75As, and Q(5/2−)

The DPAC technique was applied to investigate the temperature dependence of the hyperfine interaction of140Ce nuclei in yttrium metal. A weak damping of the anisotropy was observed, which is interpreted as a result of the short spin fluctuation timet

The number of cubic defects in In-implanted copper, silver and platinum has been determined by decorating the cubic defects with He atoms. For this, the samples were post-implanted with He+ ions at subthreshold energies. Our results, obtained by DPAC
