α-particle induced high-energy γ-ray yields from light elements

Alpha-induced thick-target γ-ray yields from light elements have been measured in the energy range 5.6 MeV ≤ Ea ≤ 10 MeV. The γ-ray yields above 2 MeV from thick targets of beryllium, boron nitride, sodium fluoride, magnesium, and aluminum were measured, and the results of this experiment were used to construct tables suitable for calculating the α-induced direct production γ-ray intensity distributions from materials. These results show a significant reduction compared with previous estimates of the distribution.
