Experimental Determination of Excitation Function Curves through the Measurement of Thick Target Yields in Liquid Targets: The Examples of the 68Zn(p,n)68Ga and 64Zn(p,α)61Cu Nuclear Reactions

“…where E is the energy of the impinging ions, E I is the initial energy of the impinging ions, Y sat (E I ) is the thick target yield at saturation at energy E I , which is usually expressed in MBq/µA sat , N A is Avogadro's number, A T is the molecular mass of the target material, ω is the percentage of the target material present in the irradiated target, ϕ is the enrichment of the target material used, σ(E) is the cross-section at energy E and S T (E) is the targetstopping power at energy E, which is usually expressed in MeV.cm 2 /g. The present work describes the determination of an excitation curve through the experimental measurement of its TTY curve by bombarding the target material of interest with several distinct initial energies, as described in [17][18][19][20]. The cross-section σ (E i ) at energy E i is then given by…”
