Resonant and nonresonant behavior of the heavy-ion reaction 14C+12C.

Abstract

The $^{14}\mathrm{C}$${+}^{12}$C reaction has been studied by a kinematic coincidence technique at 13 incident energies ranging from ${\mathit{E}}_{\mathrm{c}.\mathrm{m}.}$=19.35 to 24.9 MeV. The resonances previously reported from \ensuremath{\gamma}-ray yield measurements were observed in the equivalent excitation functions, as well as in the large angle elastic scattering data, of the present measurements. Spin assignments were made to the two resonances in this energy range. These resonances are members of a band with angular momenta several units larger than the grazing values corresponding to $^{14}\mathrm{C}$ and $^{12}\mathrm{C}$ orbiting about each other at a distance significantly outside the strong absorption radius. Other structures which were observed were unrelated to the resonant behavior.
