Abstract

Simulations of secondary neutron and gamma-ray production from the ¹¹B(d,n)¹²C and ²⁷Al(d,n)²⁸Si reactions were conducted using an MCNPX extension called MCUNED. MCUNED enables simulation of deuteron-based nuclear reactions. Deuteron libraries from the TENDL-2010 and TENDL-2011 packages were used. The simulated neutron and gamma-ray spectra were compared to experimental results provided by Taddeucci et al. and Massey et al. The method was found to be capable of simulating neutron production from ¹¹B(d,n)¹²C and ²⁷Al(d,n)²⁸Si, and gamma-ray production from ²⁷Al(d,n)²⁸Si, but not gamma-ray production from ¹¹B(d,n)¹²C. The TENDL libraries appear to be more reliable for higher mass targets because of the characteristics of the Talys code.
