// Is responsible for the management of all adjoint cross sections matrices, and for the computation of the total forward and adjoint cross sections.
|
|
// Total adjoint and forward cross sections are needed to correct continuously the weight of a particle after a tracking step.
|
|
// It is also used to sample an adjoint secondary from a given adjoint cross section matrix.
