Free Positron Lifetime and oPs lifetime distribution in Polymer

摘要：

Polystyrene was characterized by PALS in the temperature range of 20 - 400 K. Three discrete component analyses were performed on the experimental spectra. Figure 1 shows the positron lifetime (τ2) shows different behaviours for low and high temperature regions, the transient between them corresponding to the detrapping of shallow trapped electrons.
