Extreme alpha-clustering in the O-18 nucleus Academic Article uri icon

abstract

  • The structure of the 18O nucleus at excitation energies above the decay threshold was studied using 14C + resonance elastic scattering. A number of states with large reduced widths have been observed, indicating that the -cluster degree of freedom plays an important role in this N Z nucleus. A 0+ state with an reduced width exceeding the single-particle limit was identified at an excitation energy of 9.9 0.3 MeV. We discuss evidence that states of this kind are common in light nuclei and give possible explanations of this feature. Societ Italiana di Fisica / Springer-Verlag 2009.
