M050700100010 METHOD (ACTIV,COINC) The reaction yield curve measurement M050700100011 using the 8.5 min b+ residual activity of Fe-53 M050700100012 detection in coincidence with 0.38 MeV de-excitation M050700100013 g-rays from the first state of Mn-53 populated by 38 M050700100014 % of the b+ decay. M050700100015 DETECTOR (BPAIR) Positron annihilation photons counting. M050700100016 ANALYSIS (PLA) The variable bin Penfold-Leiss method for cross M050700100017 section unfolding from the yield curve.
