| Abstract |
| HfB2 with excellent thermal and mechanical properties have attracted attention to discover its radiation properties
for use fusion facilities. Geant4 has been used to simulate HfB2 neutron interaction study. For this purpose a
virtual experiment has been performed to examine suitability of HfB2 as a neutron bombardment target. The low
energy thermal neutrons produce a large number of alpha particles. The particles ratio varies tremendously up to
1.8 MeV of energy. For 10 MeV neutrons the particles spectrum follows a flat trend over 5 MeV particles
energies. The low energy thermal neutrons also produce high energy prompt gamma rays up to 20 MeV. The
backscattered neutron and forward scattered neutron spectrum has been studied.
