“…The 19 F(p, αγ) 16 O reaction is used in many areas, from detector [1,2] and dosimeter [3,4] calibration to non destructive analysis of fluorine trace with PIGE [5,6]. It was noted by many authors [7,8,9,10,11,12] that the available data as reaction cross section, photon yields, resonance energies are insufficient and in some cases inconsistent.…”
