Good morning,
I’m trying to post-processing some microscopic cross section and I’m also interested in the (n,level) reaction, MT=4, which should correspond to the sum of all other inelastic reactions (n,nX).
Despite the correct computation for few isotopes, the vast majority of isotopic cross sections obtained for this reaction are equal to zero, although the (n,Xn) reactions for the same isotopes display not zero values.
I would like to understand if somebody has any clues regarding this problem, and how to solve it without scoring all 40 (n,Xn) cross sections and then performing a sum.
Thank you in advance for your support !
