The Neutron Spectrum from theO18(d, n)F19Reaction

The neutron spectrum from the ${\mathrm{O}}^{18}(d, n){\mathrm{F}}^{19}$ reaction has been investigated. BaC${\mathrm{O}}_3$ targets enriched in ${\mathrm{O}}^{18}$ were bombarded with 2-Mev deuterons and the emitted neutrons were detected using 100- and 200-micron Ilford nuclear plates. The method of analyzing the data is discussed in detail. The results of the experiment indicates the presence of 4 excited levels in the ${\mathrm{F}}^{19}$ which had not been previously reported. These levels are at 0.9 Mev, 2.2 Mev, 5.2 Mev, and 5.5 Mev.
