The decay width of the process {eta}{yields}{pi}{sup 0}{gamma}{gamma} is calculated in the framework of the Nambu-Jona-Lasinio model. The momentum dependence of quark loops is taken into account. Three types of diagrams are considered: quark box, scalar (a{sub 0}) and vector ({rho},{omega}) pole diagrams. The obtained estimations are in satisfactory agreement with recent experimental data.
