- MCNP6 Reproduction of 40 MeV D - Li Target Experiment ?
I reproduced the experiment published by M. Hagiwara et al. using MCNP6. This experiment measures the neutron emission spectra of the Li(d,xn) reaction when 40 MeV deuterons interact with thick and thin lithium targets.The lithium target in the experiment is a cylinder with a diameter of 30 mm, and the thickness of the thick target is 21.4 mm. The source used in the experiment is a 40 MeV deuteron beam with a beam current intensity of 1 μA.The experiment refers to this website: https://nds.iaea.org/exfor/servlet/X4sGetSubent?plus=1&sub=E1986.002 . However, the data I calculated always differs from the expected results by more than 100 times. What could be the reason for this? Have I made mistakes in some of the settings?
