Title: Fusion hindrance for the positive Q -value system C 12 + Si 30

Abstract

Here, the fusion reaction 12C+ 30Si is a link between heavier cases studied in recent years, and the light heavy-ion systems, e.g., 12C+ 12C, 16O+ 16O that have a prominent role in the dynamics of stellar evolution. 12C+ 30Si fusion itself is not a relevant process for astrophysics, but it is important to establish its behavior below the barrier, where couplings to low-lying collective modes and the hindrance phenomenon may determine the cross sections. The excitation function is presently completely unknown below the barrier for the 12C+ 30Si reaction, thus no reliable extrapolation into the astrophysical regime for the C+C and O+O cases can be performed.
