Abstract
The and reactions are important for our understanding of the abundance in massive stars. The aim of this work is to report on a direct and simultaneous measurement of these astrophysically important reactions using an active target system. The reactions were investigated in inverse kinematics using as the active target gas in the detector. We measured the excitation functions in the energy range of about 2 to 6 MeV in the center of mass. We have found that the cross sections of the and the reactions are in good agreement with previous experiments and with statistical-model calculations. The astrophysical reaction rate of the reaction has been reevaluated and it was found to be larger than the recommended rate.
