Abstract

Isotopically enriched 13C targets have been bombarded with deuterons of energy 0.4–0.85 MeV. Differential cross sections have been measured for the 13C(d, p0), (d, t0), (d, α0) and (d, γ1) reactions in the form of an excitation function at 90°(lab) and angular distributions at bombarding energies of 0.41, 0.51, 0.61, 0.71 and 0.81 MeV. They have also been measured for the 12C(d, p0) reaction at 0.41 and 0.51 MeV. These data have been compared with the predictions of single and two-nucleon transfer DWBA calculations and Hauser-Feshbach statistical theory calculations. The (d, p) reactions can be described by the deuteron stripping mechanism but the (d, α) reactions proceed almost exclusively through broad overlapping levels of the compound nucleus. The (d, t) reaction appears to be an interference mixture of both these processes.

      The historical role of the (d, p) reactions in the discovery and analysis of the direct reaction mechanism is a well-known fact, that has been extensively documented in nuclear physics textbooks and review articles. Thus, it is not surprising that there exist several attempts in literature, e.g. [3–5] to explain the resulting angular distributions of the 12C(d, p0) reaction, even at very low deuteron beam energies [5], only in the framework of the direct reaction mechanism, despite the fact that through this interpretation there seem to appear significant deviations from the actual experimental data for steep backward detection angles. On the other extreme, earlier attempts for the analysis of the 12C(d, p0) reaction and the assignment of Jπ values for the relatively high-energy excited states of 14N, employed, almost exclusively, the compound nucleus mechanism, e.g. [6–11].
