Description

Abstract
The 12C + 16O reaction plays a particularly important role in both the carbon and oxygenburning
phases of stars. Fang et al. measured this reaction in a thick-target experiment a few years
ago, with both singles and particle-γ coincidence techniques down to a few nanobarns. However,
the lowest energy points suffer from large experimental uncertainties which prevent discriminating
between the Fowler model and the hindrance approach. Further measurements at low energies
with smaller errors are therefore needed to clarify the underlying physics and allow a reliable
extrapolation to the region of the Gamow peak.
This LoI is the proposal of an experiment on 12C + 16O aiming at the measurement of fusion
cross sections below the μb range with the combined set-up of AGATA and silicon detectors. The
fusion events will be identified by coincidences between the prompt γ-rays and the light charged
particles (p, α) evaporated from the compound nucleus.
The required beam time is 12 days.
