Abstract
The temperature dependences of the saturation vapor pressure of C96 and C36 fullerites and their properties along the sublimation curves are calculated using a correlation method of unsymmetrized self-consistent field that allows for strong anharmonicity of the lattice vibrations. The calculation is performed in terms of the Girifalco intermolecular potential with parameters recently determined for these fullerenes. Since experimental data on C96 and C36 fullerites are unavailable, the results of our calculations are compared with our results obtained earlier for the most commonly encountered fullerite C60. The specific features in the dependences of the properties of C96 and C36 fullerites on the number of atoms per molecule are revealed.
