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

The ²⁰Ne(p,γ) 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,γ) reaction rate is dominated by the direct capture to a barely-bound 1/2⁺ state in ²¹Na. Located just 7 keV below the one-proton separation energy (S_p), this state is a potential halo state that may enhance the direct capture. We aimed to measure the ²⁰Ne(p,γ) 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 three resonance strengths for ²⁰Ne(p,γ) that have had conflicting results from prior experiments. The results of the direct capture reaction rates and resonance strengths will be presented in this talk.
