Abstract : Present status of the C-12(alpha,gamma)O-16 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.
