摘要：

The use of Case eigen functions in the solution of Boltzmann equation for neutron transport results in an integral equation with a singular kernel. We show a solution prescription that combines a polynomial expansion for the unknown, a collocation procedure for fixing the expansion coefficients and a Double Exponential quadrature for the Cauchy principal value integral. For a set of test problems, we demonstrate the advantages of this method over the same procedure based on the TANH quadrature. (C) 2008 Elsevier Ltd. All rights reserved.
