摘要
Due to the interesting properties of hafnium diboride(HfB_2) as a ceramic, it has drawn considerabl attention from several researchers. To understand th radiation properties of HfB_2 that may be used in the nuclea industry, the interaction of this composite under neutro irradiation was studied. It is obvious that, because HfB_2 ha Boron, this composite has the potential to absorb neutron particularly in the range of thermal energy. The ^(10)B(n, a7 Li interaction is dominant among other interactions tha produce alpha particles. The results revealed that alph particles have a high fluctuation diagram following a saw tooth spectrum for thermal neutron energy, which has to b carefully analyzed. If HfB_2 is intended to be used in fusio facilities, for example in fusion reactors, its interactio with high neutrons(14 Me V) should be studied. Th results of this case showed that, in the wide range of alph energy, the amount of alpha particles is almost constant, s this continuum spectrum is almost flat and there is just small peak at 2.31 Me V that belongs to the very famou interaction [^(10)B(n, a)~7Li].
