Abstract

Excitation function of the 54Fe(p,)51Mn reaction was measured from 9.5 to 18MeV E0,p+ by activating a foil stack of 54Fe electrodeposited on copper substrates. Residual radionuclides were quantified by HPGe gamma ray spectrometry. Both 51Mn (t1/2=46.2min, =963.7keV, I+=97%; E=749.1keV, I=0.265%) and its radioactive daughter, 51Cr (t1/2=27.704d, E=320.1keV, I=9.91%), were used to indirectly quantify formation of 51Mn. Results agree within uncertainty to the only other measurement in literature and predictions of default TALYS theoretical code. Final relative uncertainties are within 12%.
