The P(L) solutions for extremely anisotropic scattering are expressed in terms of solutions for isotropic scattering. To see the use of the transformed solutions, applications for variations of the critical thickness with backward scattering are given. Numerical results are compared with the zeroth order results of elementary solutions and with the F(N) method.
