论文摘要
碳和氧气燃烧反应，特别是$^{12} $ C+$^{12} $ c融合，对于理解和解释恒星进化的后期以及灾难性二进制系统的点火和核合成阶段，例如IIA Superevae类型的灾难性二进制系统和核合成很重要。在圣母大学使用粒子$γ$重合技术与沙子（硅检测器阵列）在高强度5U Pelletron加速器上进行了新的测量。据报道，$^{12} $ C+$^{12} $ c融合的新结果与核天体物理学相关的低能量。他们在使用间接特洛伊木马法的最新测量中表现出了强烈的分歧。将讨论对天体物理场景下碳燃烧过程的影响。
Carbon and oxygen burning reactions, in particular, $^{12}$C+$^{12}$C fusion, are important for the understanding and interpretation of the late phases of stellar evolution as well as the ignition and nucleosynthesis in cataclysmic binary systems such as type Ia supernovae and x-ray superbursts. A new measurement of this reaction has been performed at the University of Notre Dame using particle-$γ$ coincidence techniques with SAND (a silicon detector array) at the high-intensity 5U Pelletron accelerator. New results for $^{12}$C+$^{12}$C fusion at low energies relevant to nuclear astrophysics are reported. They show strong disagreement with a recent measurement using the indirect Trojan Horse method. The impact on the carbon burning process under astrophysical scenarios will be discussed.
