Abstract

The radiative transfer in a freely expanding gaseous sphere, illuminated by external radiation, has been studied numerically. The absorption coefficient, spectral and spatial characteristics of the absorbed and scattered radiation, the radial dependences of excited atomic concentration have been determined, the influence of the optical thickness and the atomic radial expansion velocity on them have been investigated.
