Abstract A new method for the study of small perturbations of positron annihilation characteristics is proposed. The method is based on the direct comparison of two lifetime spectra, leading to the determination of the mean life variationΔτ and of the difference spectrum. The combined knowledge ofΔτ and of a shape parameter of the difference spectrum is often sufficient for the complete quantitative and qualitative characterization of the observed spectral modifications. Specific examples are discussed.
