The total cross section for the 24Mg(α, n)27Si reaction was determined in 10 keV energy steps from threshold to 13.1 MeV incident energy using the activation method. Variations observed in the cross section were interpreted using fluctuation theory with two notable results; firstly, that Γ, the average width of the observed fluctuations, does not vary at the rate expected over the energy range measured, and secondly that the majority of this reaction goes by a direct mechanism. This latter result was also found for the 27Al(p, n)27Si reaction after a reanalysis of published data. |
