T-approximation in the theory of normal fermi liquid

The coefficient of viscosity of³He is used as an example for considering the problem of calculating the macrocharacteristics of Fermi systems within the framework of the statistical eikonal T-approximation. It is shown that within the framework of the microscopic theory, it is possible to obtain an expression, without phenomenological parameters, which describes the viscosity not only in the temperature range in which the Landau theory is applicable but also in the range of little degeneracy.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 12–16, October, 1978.
