Dear expert. I recently simulated deuteron beam impinge at the uranium-238, in which the following nuclear reaction occurs: D+238U---->238Np+2n.
Then I calculated the yield of neptunium-238 in the uranium target. However, the results given by FLUKA are two orders of magnitude lower than those given by MCNP, PHITS, and Geant4. I don’t know what went wrong and hope the experts can help me. Attached below is my input file.
Thank you very much.

Dear user,
Indeed, this is a manifestation of a known issue raised in Bombard 186W with deuterium - #3 by cesc
A solution exists and is currently undergoing testing. It shall be shipped in an upcoming major release of the code, ideally towards the end of the year.
With kind regards,
Cesc
Thank you for your reply and wish you every success in your work.
