I would like to simulate a 4 MeV neutron beam hitting my apparatus. In particular I would like to get the proton recoil spectrum from neutron hitting a polyethylene sheet.
As DEFAULTS, should I use PRECISIO or NEUTRONS ?
I mede two simulations with these two setting and I get very different results in terms of energy spectrum of recoil protons and gammas.
From the manual I understood that the physics simulated by NEUTRONS in also included in PRRECISION.
Thanks a lot
