The (n,p) reaction cross sections of O-16 in the neutron energy range from
13.6 to 14.9 MeV were measured by the activation method. The gamma-ray coun
ting technique was applied, and the cross sections were determined relative
to the Al-27(n,p)Mg-27 reaction cross sections. The neutrons were produced
via the H-3(d, n)He-4 reaction on a SAMES T-400 neutron generator, and the
induced gamma activities were measured by a high-purity germanium (HPGe) d
etector. The efficiency calibration of the HPGe detector for gamma-ray ener
gies above 6 MeV was determined by means of gamma rays emitted from the dec
ay of Be-11. An automated fast sample transport system was combined with th
e neutron generator in order to carry out the measurements in cyclic mode.
The experimental method is described and the sources of systematic errors a
re discussed. The results obtained are compared with the experimental data
in the available literature and recent evaluations.
