Abstract
The analytic approximation is obtained for the Wigner distribution fun ction which describes the thermodynamic equilibrium state in the three -dimensional space. This approximation gives the exact result for the anisotropic harmonic oscillator and has the correct quasi-classical as ymptotic behaviour for an arbitrary potential. The iterative procedure is given to solve the Bloch equation for the Wigner function.
