In this paper we discuss the potential of positrons for the study of defects in the MOS system. It is shown that Doppler broadening measurements of the positron annihilation radiation reveals properties not detected by conventional techniques such as electron spin resonance measurements. Guiding the
## SYNOPSIS A free volume probing technique, positron annihilation lifetime spectroscopy (PALS) is used to characterize miscible blends of amorphous polycarbonate with a semicrystalline copolyester at room temperature. The paper describes the analysis required to use the PALS technique to probe th
