Multigroup Legendre Coefficients for the Diamond Difference Continuous Slowing Down Operator Academic Article uri icon


  • A set of multigroup Legendre coefficients is derived that can be used to implement the diamond difference scheme for the continuous slowing down operator in standard (unmodified) S//n codes. Calculations are performed that demonstrate the validity of these coefficients, and the superior accuracy of the diamond difference scheme relative to the standard first-order multigroup method.
