The latter is then applied to describing electromagnetic decays $π^0\to2γ$ and $π^0\to e^+e^-γ$ which entails estimates for parameters of the confining SU(3)-gluonic field in $π^0$-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field.16 pages, LaTeXHigh Energy Physics - Phenomenologytext
