Abstract : A differential equation system is obtained for the expansion coefficients of the distribution function in a monatomic rarified gas with respect to Hermite polynomials. This system contains moments up to the fifth order inclusive. The interest in these equations is supported by the desire to see general kinetic regularities in their structure, and it is not suppressed by the acknowledgement of the unreliability of their solution. From the cross section of the collision and the internal transform which characterize the mechanism of collisions between atoms, only four functionals remain in the obtained system. (Author)
