Hi Emilio,
A question similar to yours has been asked in the past, please check the link below:

Basically the answer is that unfortunately FLUKA does not yet handle this reaction at that (low) energy range. Also, I believe this feature will not be in the next FLUKA release, see link below, page 15:

Subject: [fluka-discuss]: Problen in neutron yield from deuteron beam on target
Dear Fluka experts,
I am trying to simulate the neutron production from a Be target hitten by a deuteron or a proton beam (in both cases, 100 MeV kinetic energy).
I used the USRBDX routine to measure the neutron current from the target; my problem is that, while with proton I found a non-zero current, if the beam is composed by deuteron, the current is exactly zero.
I activated several cards (I think some of them are not required); among the others
* LOW-NEUT (which I think should not be necessary, since I use DEFAULTS: PRECISIOn, is it correct?);
* IONSPLIT (in the PHYSICS card)
* PHOTONUCL
* IONTRANS
Did I miss something? Is there some interaction I need to activate in order to get the neutron yield in the case of deuteron beam? Did I use the wrong parameters somewhere?
Plase find in the attached file my imput card (in the case of proton beam, there is no difference in the card for the deuteron, except the obvious one in the BEAM card) and the output file of the USRBDX routine for both cases.
Thank you very much for you help
Best Regards
Emilio Ciuffoli
