COHERENT AND INCOHERENT ELASTIC PHOTOPRODUCTION OF [[pi].sup.0] MESON ON LIGHT NUCLEI

The paper presents calculations of the cross sections of the elastic photoproduction for [[pi].sup.0] meson on [sup.6]Li, [sup.7]Li and [sup.9]Be nuclei in terms of the impulse approximation using the intermediate coupling p-shell model. Measurements are performed in the excitation energy region of [DELTA](1232)[3/2.sup.+] resonance. The algorithm of the cross section selection is proposed for [gamma] [sup.7]Li [right arrow] [[pi].sup.0] [sup.7]Li reaction. These calculation results are in good agreement with the experimental data on the elastic photoproduction cross sections for [[pi].sup.0] meson on [sup.7]Li nucleus obtained by other authors [2].
