Prompt gamma neutron activation analysis of boron with a 241Am-Be neutron source

Design by Monte Carlo method of a thermal neutron device using a 241Am/9Be source and high-density polyethylene moderator

“…The gamma rays background with an energy of 2.223 MeV (Turhan et al, 2004) is mainly coming from the 1 H(n,γ) 2 H reaction (with a cross section σ th = 0.3327 ± 0.007 b for thermal neutrons) in hydro genous materials of moderators (Soppera et al, 2014).…”
