review text: Recognizing that the scoring accuracy is often limited by the angular sampling procedure for simulations involving highly anisotropic scattering, the authors develop a new discrete angular sampling method. This method is based on matching the first N moments of a given continuous angular scattering PDF with the first N moments of a discrete PDF consisting of a sequence of N Dirac spikes. The accuracy of Monte Carlo simulation increases with N. It is shown that the proposed discrete angular sampling method works best for highly forward peaked scattering with a high albedo. Even though both discrete method and tabular method require computational effort, the discrete method is slightly faster and more flexible than the tabular method.
