Abstract
A calculation is used to show that the kinetic energy of particles in the sublimation flux of the fullerite consisting of a mixture of C60 and C70 that is caused by a pulsed laser beam is significantly higher than the interparticle interaction energy, i.e., kT ≫ E. This finding is used to deduce a formula to determine the fullerite surface temperature from mass spectrum data on the basis of gas-kinetic equations and the data obtained by the Knudsen method for a fullerene effusion flux. The calculated and experimental results are compared. Specific features are noted for the procedure of measuring the temperature. Examples for calculating the surface temperature for other heating methods are given.
