Cross-sections for the interactions between photons and material particles,nd, it will be shown that all the other quantities, which give the radiative contribution to the transport of mass of the different species, momentum and energy, can be expressed by means of I.. It requires, however, that the expressions of the cross-section σ. and σ. for the interaction phenomena b

Boundary conditions,it is still necessary to give the appropriate boundary conditions: those pertaining to the physical quantities related to the mass particles are generally known from the mechanics of non radiating fluids, but in presence of a radiation field other conditions have to be written.

The formal solution of the equation of radiative energy transfer,When the expressions of the absorption and emission cross-sections have been specified, a formal solution of the eq. (5.8) can be easily obtained if the term (1/c) (∂/∂t) I. is assumed to be negligible: observe, however, that this is not essential assumption, and it is made only for the sake of greater simplicity of the treatment.

Simple applications,In order to show how the general equations above indicated are applied in radiative gasdynamics, two of the simplest problems are now considered; each of them involves one only transition between two states, and besides it will be assumed that the temperature of the electrons is equal to that of atoms and ions.
