β¦ Synopsis
Cross sections which is relevant in research of neutron transmutation doping of some important semiconducting materials were measured at neutron energies from 13.5 to 14.8 MeV for the reactions 75 As(n, 2n) 74 As, 75 As(n, p) 75m+g Ge, 75 As(n, a) 72m+g Ga by activation relative to the 27 Al(n, a) 24 Na reaction. Measurements were carried out by c-detection using a coaxial HPGe detector. Natural realgar (As 2 S 2 ) powder of 99.9% purity was used as samples. Fast neutrons were produced by the T(d, n) 4 He reaction. The results obtained are compared with existing data.
