Content

The model of coherent $pi^0pi^0$ mesons photoproduction on simplest nuclei of hydrogen and deiterium in the region $E_{gamma}le1.4$ GeV is presented. Two pion rescattering amplitude in process $pi^+pi^-topi^0pi^0$ is taken into account from phenomenological fit is accurately defined it in treshold region as well as up to 1100 MeV relative energy in $pipi$ c.m. Strong dependence of the result on the rescattering amplitude is also discussed.
