Abstract

In a recent experiment performed in Naples by using the TTT-3 tandem accelerator, the 19F(p, α0) reaction has been investigated at low bombarding energies, Ep = 0.6–1 MeV. Excitation functions and angular distributions have been obtained by using several solid state detectors preceded by thin aluminium absorbers. By analysing angular distributions in terms of Legendre and cosine polynomials, a few spectroscopic ambiguities concerning the excited states of the compound nucleus, 20Ne, in the excitation energy region E* = 13.4–13.8 MeV, have been solved. Moreover, this reaction plays an important role for the description of the fluorine nucleosynthesis. For this reason, the astrophysical S-factor has also been extracted and the results have been compared with the literature data.
