Analytic approximations of the H-function based on different DPN procedures
Three approximate analytic expressions for the H-function are derived by using ordinary and flux decomposition DPN method. The accuracy of approximations is examined and comparison with similar formulas of the other authors is performed. As an application of the approximate H-functions the energy-dependent particle albedo problem is treated analytically. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
