Abstract
The range of the proton-antiproton annihilation was calculated for antiproton with energy near 1 Bev. The point is to get the range of pure annihilation interaction, separating the effect of pion production. It was found that the root mean square of this range is given by (1.19\ifmmode\pm\else\textpm\fi{}0.07)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}13}$ cm almost independently of the energy.
