Abstract
Abstract The asymmetric structure of the luminous neutral barium cloud in chemical release experiments is studied for various optical thicknesses. Three different kinds of density distribution functions (uniform, Gaussian and shell) of the neutral barium cloud are considered. When the barium cloud is optically thick, due to the absorption of the sun light, a crescent structure in radiance is found in the dayside of the barium cloud . For a shell distribution neutral barium cloud, we find an additional small crescent structure in the nightside of the cloud. For an optically thin neutral barium cloud, the sun light can go through the sphere without absorption, so that the radiance distribution is similar to the density distribution of the neutral barium cloud.
