41 // September-October 2009. Implementation of the mode where the adjoint cross sections are scaled such that the total used adjoint cross sections is in
42 // most of the cases equal to the total forward cross section. L.Desorgher

44 //-------------------------------------------------------------
45 // Documentation:
46 // Is responsible for the management of all adjoint cross sections matrices, and for the computation of the total forward and adjoint cross sections.
47 // Total adjoint and forward cross sections are needed to correct the weight of a particle after a tracking step or after the occurence of a reverse reaction.
48 // It is also used to sample an adjoint secondary from a given adjoint cross section matrix.
