Alpha structure of <sup>16</sup>O at high excitation energy via <sup>3</sup>He + <sup>13</sup>C nuclear reactions
These proceedings report a new data analysis aimed to the study of low-spin, high excitation energy states in the spectroscopy of the 16 O nucleus around 24 MeV excitation energy. After a careful spectroscopical analysis, based on the Legendre polynomials decomposition of angular distribution data obtained in 3 He+ 13 C reactions at low energies, it was possible to determine the J π assignments for two high-lying states at E x ≈ 24.1 and ≈ 24.5 MeV. Some conclusions are also drawn regarding the presence of pronounced 4 α structure of these states, based on the analysis of the branching ratios of the α 2 to the α 0 channels in the 16 O compound nucleus decay.
