Abstract
Does the diffusion coefficient of a photon depend on time or the probability of absorption ? To find an answer to the question, photon transport in a medium of infinite extent is analyzed using the method of moments. It is pointed out that if is defined so as to make it depend on or , it will also depend on the experimental conditions; that the parameter which enters the stationary diffusion equation is in general different from that entering the transient version; and that a hitherto unused non-Markovian partial differential equation may be used for treating photon transport.
