The monoenergetic integral transport equation is solved in an approximate manner by separating the integral into an asymptotic component plus a transient boundary component. Solutions to the resulting equation are obtained with only a modest increase in complexity over diffusion theory. The method is illustrated by several examples in which significant improvement over diffusion theory is obtained.
