  The isochoric thermal conductivity of gama-O2 has been studied on samples of
varying density in the temperature interval from 44 K to the onset of melting.
The thermal conductivity of nearly free sample decreases at rising temperature
along the isochores. It is shown that the absolute value of thermal
conductivity in the gama-phase of O2 is close to its lower limit and most of
the heat is transported by "diffusive" modes. The growth of thermal
conductivity in gama-O2 is attributed to the decay of the phonon scattering at
the rotational excitations of the molecules and at the short-range magnetic
order fluctuations at rising temperature.
