The reaction [sup 12]C(α,γ)[sup 16]O has a strong influence on both stellar evolution and nucleosynthesis after the helium burning stage in massive stars. The E1 amplitude of this astrophysical important reaction was measured in inverse kinematics using a [sup 4]He windowless gas target and an intense [sup 12]C ion beam in combination with an array of HPGe detectors. The results of this measurement were extrapolated to the relevant energy for helium burning (E[sub 0]=300 keV) using the R-matrix formalism of nuclear reactions. The error on the extrapolated value was determined via a Monte Carlo procedure. The results of this experiment and of their extrapolation to E[sub 0] are presented and compared with previous data. © 2002 American Institute of Physics. [ABSTRACT FROM AUTHOR]
