Excitation function and thick target yield of the Ar-40(alpha,p)K-43 reaction: Production of K-43

The excitation function of the Ar-40(alpha,p)K-43 nuclear reaction has been measured via the activation technique using stacked gas cell targets. Absolute cross section values were deducted from the experimental data and were compared with theoretical predictions calculated by means of the STAPRE code. Thick target yields of K-43 were calculated from the experimental data. A target system working in static (batch) or in recirculating gas flow mode has been developed to produce K-43.
