31 // An adjoint CS matrix is used by the model of a reverse process to sample
32 // an adjoint secondary (being equivalent to a forward primary). It represents
33 // the integration over the energy of the adjoint secondary (therefore the
34 // forward primary) of the differential cross section of the equivalent forward
35 // discrete process (Ionisation, Brem, PE effect, Compton,..). Each reverse
36 // model has its own cross section matrix for a given cut, material couple. It
37 // is therefore recomputed after a modification of the cuts by the user.
