Abstract
The effect of magnesium sulfate on the structural parameters of aqueous lecithin solutions has been studied using electron-positron annihilation spectroscopy. Changes in the lifetime and annihilation of ortho-positronium in the solutions arise from the introduction of low concentrations of dopant ions. The experimental results are interpreted in terms of the modifying role of magnesium cations and sulfate ions.
