 //              Continuous processes acting on adjoint particles to correct continuously their weight during the adjoint reverse tracking.
+//              Thi process is needed whene the adjoint cross section are not scaled such that the total adjoint cross section match the total forward cross section. 
+//              By default the mode where the total adjoint cross section is equal to the total forward cross section is used an therefore this along step weight 
+//              correction factor is 1.
+//              However in some cases (some energy ranges) the total forward cross section or the total adjoint cross section can be null, in this case the along step 
+//              weight correction is neede and is given by exp(-(Sigma_tot_adj-Sigma_tot_fwd).dx)
