Abstract

The quantification of isotopes content in materials is extremely important in many research and industrial fields. Accurate determination of boron concentration is very critical in semiconductor, superconductor and steel industry, in environmental and medical applications as well as in nuclear and astrophysics research. The detection of B isotopes and of their ratio in synthetic and natural materials may be accomplished by gamma spectroscopy using the ¹⁰B(p,)⁷Be and ¹¹B(p,)¹²C reactions at low proton energy. Here, the ¹⁰B(p,)⁷Be cross section is reported in the center of mass energy range 0.35 to 1.8 MeV. The keV rays were detected at and using a NaI(Tl) and an HPGe detectors, respectively. In the presented energy range, previous cross section data revealed discrepancies and normalisation issues. Existing data are compared to the new absolute measurement and discussed. The present data have been subtracted from a previous measurement of the total cross section to derive the contribution of the channel.
