Dear FLUKA experts:
Please forgive my intrusion. I would like to inquire about when the cutoff energy value for nuclear reactions (1.1 MeV/n) in FLUKA code could be modified. In fact, some reactions (such as D+3He) have considerable cross sections below this cutoff, which is quite important for calculating nuclear reaction physics.
The figure below shows the reaction cross section for a 3He beam bombarding a D target, with the horizontal axis representing the 3He energy in the laboratory frame.
I sincerely hope that FLUKA developers can resolve this issue as soon as possible. Thank you for your generous help and patient response. I wish you the very best .
