V originále

The production of fluorine-18 represents a strong source of neutrons. Its characteristics are of interest for the community and for further applications. The neutron spectra of secondary neutrons from the reactions of protons on a 18 O-enriched water target were acquired at ten different angles with stilbene scintillation spectrometry. The absolute neutron yield from the same target was measured using the manganese bath technique and found to be 2.15 x 10 10 / mu C. The obtained neutron spectrum and angle-dependent yield are presented. Comparison of the experimental data with simulations revealed only limited agreement. JENDL5 shows the best agreement for the neutron spectra in forward angles, while TENDL-2021 gives the best prediction of the absolute angle-dependent neutron yield.
