Abstract: The results of earlier calculations of τ → (π$^{0}$, η, η′, K$^{0}$)K$^{–}$ν$_{τ}$ processes in the extended Nambu–Jona-Lasinio model are compared. The full widths of these processes are given. The contributions of intermediate vector and scalar mesons both in the ground state and in the first radially excited one (K*(892), K*(1410), K0*(800), K0*(1430), ρ(770), and ρ(1450)) are taken into account. The results are in reasonable agreement with the experimental data.
