The quantum correction to the ''classical'' nucleon mass is calculated, taking into account radial fluctuations around the hedgehog Skyrme soliton. The quantum correction pushes down the Skyrme-soliton mass if one chooses the arbitrary mass scale of the theory /ital M//similar to//ital m//sub /rho//, where /ital m//sub /rho// is the /rho/-meson mass. The nucleon--/Delta/-isobar mass difference is obtained correctly when the parameter /ital F//sub /pi//=125 MeV. This value of /ital F//sub /pi// is in better agreement with the pion-decay constant /ital F//sub /pi//=186 MeV than the value /ital F//sub /pi//=108 MeV that was obtained previously in the framework of the Skyrme model without the consideratiion of the vibrational quantum corrections.
