PRESENT STATUS AND PERSPECTIVES IN NUCLEAR ASTROPHYSICS STUDIES OF THE 12C(α,γ)16O REACTION

Present status of the 12C(α,γ)16O cross section knowledge at stellar helium-core burning temperature is presented. Its consequences on the reaction rate uncertainties are discussed considering available models to extrapolate experimental results down to stellar helium-core burning temperature. Some experimental perspectives to reach the desired precision at stellar temperatures are described.
