摘要：When laser radiation is allowed to pass through the diffusion region separating the two liquids in aChristiansen cell, beautiful circular halo is observed on the screen. The pattern of this diffraction halo changes withtime. In the present work we have studied this diffraction halo and its time evolution. It has been observed that there isa definite co-relation between the shape of the diffraction halo and width of the diffusion region. The time evolution ofthis diffraction halo indicates that as diffusion region increases the circular halo becomes elliptical and finally straight.It may be noted that this type of diffraction halo and its time evolution is not reported in any earlier works inconnection with Christiansen effect. It is believed that the time evolution of this diffraction halo will have practicalapplication in diffusion study between two molecules.
