On the radiative heat exchange between spherical particles at small distances

On the radiative heat exchange between spherical particles at small distances

The radiative heat exchange of spherical dipole particles is recalculated in the framework of fluctuation electrodynamics. We show that the correct numerical coefficient in the resultant integral expression equals 4/π, which is in great contrast with the value obtained by other authors.
