EN The positron lifetime spectra in iron defected with a beam of Bi+51 and Kr+27 ions of energies 670 MeV and 240 MeV, respectively, were investigated. These spectra were analysed by an appropriate separation in 1, 2 or 3 components. It has been found that the experimental data best fit to the assumed [...]

EN The heavy ion ranges in amorphous SiO2 have been calculated by using a technique based on solution of first order ODE’s. Br, Au, Hg, Bi, projectiles have been chosen as incident ion. Since the target is assumed to be amorphous, Bragg’s rule can be used to calculate electronic and nuclear stopping po[...]

EN This paper deals with the luminescence of silica (KV-type) induced by beam of hydrogen ions with the energy of 210 keV per nucleon. An average implantation dose of up to 3.5 × 1021 cm–3 (5 × 1010 Gy) was accumulated during irradiation over an extended period. The luminescent spectra consisted of the[...]
