Thank you Paola.
Yes I work on pB fusion so I am interested in some reactions : 11B(p,3alpha) through 8Be* or 8Be, 10B(p,alpha)7Be and 14N(p,alpha)11C...
With mgdraw.f I can see from which reaction alpha come from.

But I have to compare this simulation with an experiment and I undervalue alpha number of a factor 10 sometimes.

So I would like to have access to the cross sections of reactions p/B and p/N used by FLUKA. How I can do to do that?

Thank you

Hello
no, Fluka does not use TENDL, at least not for proton induced reactions:
It has its own parametrization of proton-nucleus cross sections.
For low energy neutrons, some of the materials are treated using TENDL
data, however most datasets are derived from ENDF
In the plot, you mean 11B(p,3alpha), right?
Regards
Paola
