To the theory of Ps formation. New interpretation of the e+e+ lifetime spectrum in water

A brief review of ideas behind the blob model is given. For the first time positron annihilation lifetime spectrum in liquid water is deconvoluted without a usage of the multi-exponential approach, but on the bases of the blob model, which suits well for description of the intratrack processes including positronium (Ps) formation in condensed molecular media. All adjustable parameters in the blob model have clear physical meaning. Excellent agreement with the experiment is obtained.
