The new criterion of detonation initiation is proposed: critical initiation energy E is equal to work of extending detonation products on layer length equal to the longitudinal cell size b of multifront detonation. Initial layer radius R gets as diffraction radius of detonation wave (diffraction on right angle) in the moment of collision of an axial rarefaction waves up to a gas charge axis. The formulas for the critical initiation energies for plane, cylindrical and spherical detonation waves are received. Calculated results ar well correlated with correct experimental data.
