The positron annihilation lifetime spectroscopic technique was applied to study nanocrystals formation during controlled crystallization of a chalcogenide glass 51GeS 2 -9Sb 2 S 3 -40PbS, which was thermally treated at 330 Β°C for up to 15 h. The technique provided valuable information for in depth u
## Abstract The positron annihilation lifetime spectroscopy (PALS) technique is used to measure volume relaxation in physically aged glassy polycarbonate. The relaxation times and activation energy calculated for the isothermal relaxations in the aged polycarbonate are greater than those parameters
