Continuous-energy adjoint Monte Carlo theory of coupled continuum/discrete radiation transport

The fundamental problems encountered in any attempt to include a description of the production and transport of monoenergetic (discrete) radiation in a continuous-energy adjoint Monte Carlo procedure are explored. An idealized, one-dimensional, double-scattering transmission problem is employed in order to devise a method for overcoming these difficulties. This method is then generalized to an adjoint Monte Carlo procedure for describing coupled continuum/discrete radiation transport. 13 refs
