Abstract

We present some preliminary calculations on cross sections for the breakup of ${}^{16}O$ around 100 MeV/nucleon with emphasis on the effect of nuclear breakup on the angular distributions. Underlying the results of these calculations, the possibilities and problems of extracting the astrophysical S factor for the ${}^{12}C$ (α,γ $)^{16}$ O reaction at very low energies are discussed. Some considerations on the experimental conditions for a ${}^{16}O$ breakup experiment aiming at this astrophysical information are given.
