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