We present new experimental measurements of resonance strengths in the astrophysical ²³Al($p,\gamma$)²⁴Si reaction, constraining the pathway of nucleosynthesis beyond ²²Mg in X-ray burster scenarios. Specifically, we have performed the first measurement of the ($d,p$) reaction using a radioactive beam of ²³Ne to explore levels in ²⁴Ne, the mirror analog of ²⁴Si. Four strong single-particle states were observed and corresponding neutron spectroscopic factors were extracted with a precision of ∼20%. Using these spectroscopic factors, together with mirror state identifications, we have reduced uncertainties in the strength of the key ℓ = 0 resonance at $E_r$ = 157 keV, in the astrophysical ²³Al($p,\gamma$) reaction, by a factor of 4. Our results show that the ²²Mg($p,\gamma$)²³Al($p,\gamma$) pathway dominates over the competing ²²Mg($\alpha ,p$) reaction in all but the most energetic X-ray burster events ($T>0.85$ GK), significantly affecting energy production and the preservation of hydrogen fuel.

我们提出了天体物理学²³ Al($p,\gamma$) ²⁴ Si 反应，在 X 射线爆发情景中将核合成途径限制在^{22 Mg 之外。}具体来说，我们已经对 ($d,p$) 反应使用²³ Ne 的放射性束来探索^{24 Ne（ 24} Si的镜像类似物）中的能级。观察到四种强单粒子状态，并以~20%的精度提取了相应的中子光谱因子。使用这些光谱因子以及镜像状态识别，我们减少了关键ℓ = 0 共振强度的不确定性${乙}_r$= 157 keV，在天体物理学中²³ Al($p,\gamma$) 反应，增加了 4 倍。我们的结果表明，²² Mg($p,\gamma$) ²³铝($p,\gamma$) 途径在竞争的²² Mg($\alpha ,p$) 除了最有活力的 X 射线爆发事件之外的所有反应 ($吨>0.85$GK)，显着影响能源生产和氢燃料的保存。
