Excitation function of 54 Fe(p, α ) 51 Mn from 9.5 MeV to 18 MeV.

Excitation function of the ⁵⁴ Fe(p, α )51Mn reaction was measured from 9.5 to 18 MeV E 0 , p + by activating a foil stack of ⁵⁴ Fe electrodeposited on copper substrates. Residual radionuclides were quantified by HPGe gamma ray spectrometry. Both ⁵¹ Mn ( t _{1 / 2} = 46.2 min, 〈 E β + 〉 = 963.7  keV , I β + = 97 % ; E _γ = 749.1 keV, I _γ = 0.265%) and its radioactive daughter, ⁵¹ Cr ( t _{1 / 2} = 27.704d, E _γ = 320.1 keV, I _γ = 9.91%), were used to indirectly quantify formation of ⁵¹ Mn. Results agree within uncertainty to the only other measurement in literature and predictions of default TALYS theoretical code. Final relative uncertainties are within ±12%.
