Positron annihilation lifetime and Doppler broadening study in 50MeV Li3+ ion irradiated polystyrene films

Swift heavy ion (SHI) irradiation of polymeric materials results in the change of their free volume properties which have strong correlation with their macroscopic properties. The modification depends on the polymer and ion beam parameters, namely ion energy, fluence and ion species. Polystyrene fil...
