Astrophysical S-factor for ${}^{16}$O+${}^{16}$O within the adiabatic molecular picture

Abstract

The astrophysical S-factor for ${}^{16}$O + ${}^{16}$O is investigated within the adiabatic molecular picture. It very well explains the available experimental data. The collective radial mass causes a pronounced resonant structure in the S-factor excitation function, providing a motivation for measuring the ${}^{16}$O + ${}^{16}$O fusion cross section at deep sub-barrier energies.
