Description
A molecular model for positron complexes is developed and used to study the effects of the nucleus-positron distance long-range regime on the 2γ annihilation rates (Γ) of atomic complexes. The available data for Γ of some systems are then rationalized on its basis and some predictions are made. The model is shown to be capable of generating information on positron positioning and of making predictions of values of Γ in molecular complexes as well
