چکیده

We outline a new kinetic theory for positrons in soft matter, which blends together cross sections for positrons scattering from single molecules, with the structure function of the medium as a whole. Numerical results are presented for positrons in liquid argon, where negative differential conductivity arises from both positron formation and the structure of the medium.

Calculation of positron states and annihilation in solids: A density-gradient-correction scheme.

The generalized gradient correction method for positron-electron correlation effects in solids @B. Barbiellini et al., Phys. Rev. B 51, 7341 ~1995!# is applied in several test cases. The positron lifetime, energetics, and momentum distribution of the annihilating electron-positron pairs are considered. The comparison with experiments shows systematic improvement in the predictive power of the t...
