Abstract

The C13(d,n)N14 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 N14 and to investigate an anomalous angular distribution from previous work on this reaction. A table of θ2, the reduced widths for stripping, is given along with a brief discussion of the consistency of the N14 shell-model assignments with the stripping analysis. The second experiment reported in this paper on the O18(d,n)F19 reaction was based on the suggestion that neutrons which leave F19 in its 2.78-MeV level might be undergoing spin-flip stripping. A more strongly forward angular distribution than an Lp=2 distribution was found; this Lp 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.
