This project will develop the quantum mechanical theories needed to describe the complex processes in stellar fusion reaction such as 12C + 12C. Studying such reactions is key to understand carbon burning in massive stars in pre-supernova phase. The fusion of 12C + 12C is characterized by resonant enhancement, in due part to molecular states in the 12C + 12C system. Recent work by the Surrey group (Phys. Rev. C 97, 055802) has demonstrated the applicability of a time-dependent wave packet approach to explaining some of the resonance behaviour. In this project, we will combine this approach with a fully microscopic theory (time-dependent generator coordinate method) to refine our understanding, and include clustering effects. By linking the more microscopic theory to the computationally-efficient wave packet method, we will be able to apply the theory to nuclei far from stability

该项目将开发描述恒星融合反应（例如12c + 12c）中复杂过程所需的量子机械理论。研究这种反应是了解苏植物前恒星中大量恒星中碳燃烧的关键。 12c + 12c的融合的特征是共振剂增强，这是由于12c + 12c系统中的分子状态的一部分。 Surrey Group（Phys。Cev。C 97，055802）的最新工作证明了时间依赖性波数据包方法的适用性来解释某些共振行为。在这个项目中，我们将将这种方法与完全显微镜理论（时间依赖性发生器坐标方法）相结合，以完善我们的理解并包括聚类效应。通过将更多的微观理论与计算效率波数据包方法联系起来，我们将能够将理论应用于远非稳定性的核
