Re: [fluka-discuss]: 7Li(p,n)7Be and 9Be(p,n)9B reactions in the PRECISIO defaults ?

Dear Bertrand,

the mentioned direct reactions are not (yet) implemented in FLUKA as such,
see also

As a side note, the only loose link the PRECISIO settings collection has
got with them is concerning the proton and neutron transport thresholds,
affecting the possibility that a p+Li occurs (it doesn't if the proton
transport threshold is higher than the projectile energy, but this is not
your case) and the secondary neutron transport (E<20MeV neutrons are
transported in the case of PRECISIO), respectively. Still, for the reasons
mentioned above, one should not count on getting the expected peaked

Kind regards
