Description
The CNO-cycle is the dominant hydrogen burning process in stars above a temperature of 17 million Kelvin. The $^{12}$C(p,$\gamma$)$^{13}$N reaction rate is dominating the rate of this cycle in the initial phase and in the outer shells of the burning zone. Furthermore, this reaction affects the abundance ratios of $^{12}$C to $^{13}$C in stars with masses slightly above solar mass. The cross section of the $^{12}$C(p,$\gamma$)$^{13}$N reaction has been re-measured, leading to an improved extrapolation to astrophysically relevant energies.
The methods and results of two measurements of this cross section will be presented: First, at $130\,$keV to $450\,$keV in inverse kinematics overground. Second, at $330\,$keV to $640\,$keV at the Felsenkeller underground laboratory.
