In the process of electron-positron annihilation and the $\\tau$ - lepton decay the contributions of the intermediate $\\rho(770)$ vector meson in the ground and first radially excited state are taken into account. The theoretical prediction for the decay $\\tau\\rightarrow \\rho(770)\\eta\\nu_{\\tau}$ is given.
