| Previous measurements of 20Ne(p,γ) 21Na have provided inconsistent values for both the 1169-keV resonance strength as well as lower energy direct capture cross sections. In this work, direct capture cross sections were measured relative to the resonance using solid implanted targets. An absolute measurement of the resonance strength was then made using a gas target. From these new results, the S factor and reaction rates were calculated and compared to accepted values. The final rates are approximately 25% lower than those previously used. |
