Abstract: These proceedings report a new data analysis aimed to the study of low-spin, high excitation energy states in the spectroscopy of the 16O nucleus around 24 MeV excitation energy. After a careful spectroscopical analysis, based on the Legendre polynomials decomposition of angular distribution data obtained in 3He+13C reactions at low energies, it was possible to determine the Jπ assignments for two high-lying states at Ex ≈ 24.1 and ≈ 24.5 MeV. Some conclusions are also drawn regarding the presence of pronounced 4α structure of these states, based on the analysis of the branching ratios of the α2 to the α0 channels in the 16O compound nucleus decay.
