This paper presents calculations of the fifth-order nonlinear optical susceptibilities of sodium vapor responsible for the third harmonic generation, degenerated six-wave mixing as well as for the fifth-order nonlinear Kerr effect. The values of the nonlinear susceptibilities were obtained applying the quantum-mechanical perturbation theory of the atomic wave function using values of the dipole matrix elements of 12 lowest atomic energy levels and are presented as functions of the wavelength within a wide spectral range from ionization wavelength of 241.3 nm to 2400 nm. Presented data can be used further for the theoretical modelling of various nonlinear optical processes.
