| Abstract: | Analysis of experimental data on the relaxation of freely moving hot niobium and tungsten clusters shows that they are cooled
as a result of radiative emission. The absorption cross sections per atom of niobium and tungsten clusters in the temperature
range 3100–3700 K are (4 −7)×10−18 cm2, and the absorption process loses its resonant character at these temperatures.
