Abstract

The $C^{13} (d, n) N^{14}$ reaction has been restudied with the purpose of obtaining absolute differential cross sections. The intention has been to extract stripping reduced widths for the four lowest energy levels in $N^{14}$ and to investigate an anomalous angular distribution from previous work on this reaction. A table of $θ^{2}$ , the reduced widths for stripping, is given along with a brief discussion of the consistency of the $N^{14}$ shell-model assignments with the stripping analysis. The second experiment reported in this paper on the $O^{18} (d, n) F^{19}$ reaction was based on the suggestion that neutrons which leave $F^{19}$ in its 2.78-MeV level might be undergoing spin-flip stripping. A more strongly forward angular distribution than an $L_{p} = 2$ distribution was found; this $L_{p}$ value had been suggested if the 2.78-MeV level had a 7/2+ assignment and spin-flip stripping is an important mechanism. Since the experiment was completed, evidence has appeared which favors a low spin value for the 2.78-MeV level and invalidates the reaction as an indicator of the spin-flip mechanism.
