Study of the 20Ne(p,γ) reaction rate using GRIFFIN γ-ray detectors coupled with the DRAGON recoil spectrometer at TRIUMF*

The 20Ne(p,g) reaction is the reaction in the Ne-Na cycle that limits the production of 22Na, an important radiotracer, in O-Ne nova explosions (T=0.1-0.4GK). In this temperature range, the 20Ne(p,g) reaction rate is dominated by the direct capture to the barely-bound 1/2+ state in 21Na. Located just 7 keV below the one-proton separation energy (Sp), this state is likely a halo state which may enhance the direct capture. We aimed to measure the 20Ne(p,g) reaction rate near the Gamow window using the DRAGON recoil spectrometer coupled for the first time with six GRIFFIN HPGe clover detectors at TRIUMF. We also measured resonance strengths for three resonances that have had conflicting results from prior experiments.  In this talk, the preliminary results of the direct capture reaction rates and resonance strengths will be shown.
