Estimates for parameters and characteristics of the confining SU(3)-gluonic field in π⁰-meson from one- and two-photon decays

On the basis of the confinement mechanism earlier proposed by author the electric formfactor of $\pi^0$-meson is nonperturbatively calculated. The latter is then applied to describing electromagnetic decays $\pi^0\to2\gamma$ and $\pi^0\to e^+e^-\gamma$ which entails estimates for parameters of the confining SU(3)-gluonic field in $\pi^0$-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field.
