This study provided deep understanding of the 12C formation process from three alpha particles (4He nuclei), by means of a three-body quantum mechanical reaction theory. Plain formulation of the ternary fusion process (TFP) and differentiation from other existing models are very important outcomes of this study . Collaboration with experimental group to measure the TFP process was also initiated; they have successfully carried out a measurement very recently. Besides, some important modifications on the reaction model have been done, which fruitfully produced several reaction works.

这项研究通过三体量子力学反应理论，对三个α粒子（4 He核）形成12 C的过程提供了深入的理解。三元融合过程（TFP）的简单表述和与其他现有模型的区别是本研究的重要成果。还开始与实验小组合作测量全要素生产率过程;他们最近成功地进行了一次测量。此外，本文还对反应模型进行了一些重要的修改，并取得了一些成果。
