Abstract

The main parameters and technical features of the PrimEx experiment conducting in Jefferson Lab (USA) are presented. One of the main parts of the PrimEx setup-electromagnetic calorimeter is described in details. Value of π0 meson decay width into two γ-quanta, obtained from PrimEx 2004 year data is Γ(πo → 2γ) = 7.82 eV 2.2% (stat.) 2.1% (syst.)
