论文摘要
我们使用高分辨率$^{32} {\ rm s}(d,t)$测量来调查可能影响$^{31} $ s中的6401(3)kev state,可能会影响$^{30} {30} {\ rm p}(p,γ)$核反应速率(p,γ)$核反应速率(coxy-gen-gen-gen-gen-gen-gen-nove)我们的数据显示出具有很高意义的无效假设 - 状态不存在。此外,数据还表明存在于6648(4)KEV的迄今未报告的状态。该状态对应于$^{30} {\ rm p}(p,γ)$共振的价格为$ 517(4)$ keV,位于Gamow窗口高窗口下方的峰值NOVA温度约为0.4 Gk的峰值。
We use a high resolution $^{32}{\rm S}(d,t)$ measurement to investigate the claimed existence of a 6401(3) keV state in $^{31}$S that may affect the $^{30}{\rm P}(p,γ)$ nuclear reaction rate in oxygen-neon (ONe) novae. Our data are shown to exclude the null hypothesis - that the state does not exist - with high significance. Additionally, the data also suggest the existence of a hitherto unreported state at 6648(4) keV. This state corresponds to a $^{30}{\rm P}(p,γ)$ resonance at $517(4)$ keV, located below the higher edge of the Gamow window for peak nova temperatures of about 0.4 GK.
