In this work we used Positron Annihilation Spectroscopy (PAS) and Electron Paramagnetic Resonance (EPR) to investigate the properties of vacancy defects produced by low energy electron irradiation. N-doped 3C-SiC and 6H-SiC monocrystals have been irr

This paper presents positron lifetime results which give information on the nature of vacancy defects induced by electron irradiation in bulk nitrogen doped (nD-nA= 2.3x1017 cm-3) Cree 6H-SiC. The electron irradiations have been performed at differen

The behaviour of helium implanted in sintered uranium dioxide disks has been investigated as a function of annealing temperature. UO2 disks have been implanted with 1 MeV 3He ions at a fluence of 1 × 1016 3He cm−2 using a Van der Graaff accelerato

In this study, we have characterized the isothermal annealing (300°C) of 86Kr32+ ion tracks in Durango fluoroapatite by means of channeling Rutherford backscattering spectrometry (CRBS) and chemical etching. The CRBS results were obtained for four 8

With the aim of characterizing damage along nuclear tracks in apatite, Durango fluoroapatite monocrystals were irradiated under a high fluence 86 Kr ion beam at the G.A.N.I.L. (Grand Accelerateur National d'Ions Lourds, Caen, France). The resulting i

Thin films have been deposited by radio-frequency magnetron sputtering, using LiCoO2, LiNiO2 and LiNi0.7Co0.3O2 targets, in argon or Ar/O2 gas mixture. The composition of the thin films has been determined by proton induced gamma-ray emission (PIGE)
