Positron lifetime and Doppler broadening measurements have been used to study the annealing behaviour of deformed Gd between 290 and 700 K . The observed recovery stage a t about 370 K is attributed to dislocations annealing. Positronenlebensdauer-und Annihilationslinienbreite-Messungen wurderi ang

Positron annihilation studies within the standard methods in copper layers electrodeposited on the copper substrate are presented. The main interest was focused on the studies of the S-parameter evaluated from the annihilation line as a function of the thickness of the covered layer. The thickness o
Positron lifetime spectra have been measured on plastically deformed Zn-doped p-type GaAs with strain ranging from 0 to 15% at room temperature. The lifetime spectra were analyzed using PATFIT and MELT programs. Two lifetime components were observed in deformed samples. The second lifetime t 2 $ 400
