Measurements of low-energy (d,n) reactions for BNCT

Neutron yields and energy spectra have been measured for various deuteron-i nduced reactions at low energy. Neutrons of energy >100 keV emitted in the Be-9(d,n)B-10, C-12(d,n)N-13, and C-13(d,n)N-14 reactions at E-d = 1.5 MeV were detected at five angles by means of liquid scintillator detectors. Whi le low-energy neutrons were observed in all studied reactions, only C-13(d, n)N-14 is characterized by a relatively large yield with spectral features potentially interesting for an accelerator-based neutron source for BNCT.
