Abstract

A molecular dynamics simulation of helium diffusion in solid CaF<subscript>2</subscript>, SrF<subscript>2</subscript>, and BaF<subscript>2</subscript> was carried out using the empirical pair potentials reproducing the experimental strong binding of helium to cations in these crystals. The model diffusion coefficients and activation energies are determined. [ABSTRACT FROM AUTHOR]
